I had a build 509 on my friend's computer, but before I could get to it again Metaquotes killed it and replaced it with build 600. Once again cannot import history files with FSB. The history files do download into the MT4/history/Demo01 file, but cannot import them into FSB. I have tried serfel's Debug file but that did not work for me. Anyone else try that? I have gone back to footon's recommendation to save files to FSB data file. The drawback is the lack of 1 minute data, but some is better than none. I can export MT4 files from the history center to excel or open office, but that is the same amount of data as footon's "save as" method. Are the history files encrypted? I have never seen data files that look the way they do. I don't even see any numbers. I've tried opening them with excel or open office and it makes absolutely no sense. And one more question, are  jforex  users having the same issue? or is this a metaquotes issue only. Any response welcome Thankyou.

If you place only .exe in directory your FSB and run it, and what's not work?

**UPDATE: On further inspection, it is true I can save data from MT4 charts, but whereas before I was downloading 1 minute data from at least several years past(if not more) I am now only able to retrieve about 3 months  of 1 min data

That's a question to broker/metaquotes.

It is definitely not a problem on your end, the MT update had also a change in .hst files (MT history files) as I just remembered. When the flood of updates stops, and the platform regains its relative stability, and the developer returns back home, then it's most probable that the history file import function can be fixed. The source of this problem is metaquotes.

Unfortunately there are more problems with the update, most importantly FST connection with MT. We are very lucky to have Sergei (Serfel) here, who has produced the fixes. BUT, build 610 might not work yet, unknown bugs from MT can show up, there might be newer builds coming, so adventurous times to say the least. Testing and verifing it all works is of most importance before going live.

For the time being, we can conclude the import function is not working. My question: does the data you download show up nicely on MT charts? If it does, try to save it manually File->Save As->FSB Data directory.

You get the point. Same message for every symbol and every timeframe. What am I doing wrong here? I never had a problem before importing history files. Then, after updating MT4 program, started having this problem. I am running MT4 version 4.00, Build 610. And FSB version 3.0.2.0.  I am downloading metaquotes from FXCM Demo 01 server. Any help, please, is greatly appreciated!!

A few things I have already tried: I've uninstalled and reinstalled both FSB and MT4 platform. I've downloaded MT4 history numerous times. For the record, MT4 History files does contain data. I've deleted all early history files, e.g. 1971, 72, 73, etc., which contain no data. However, data never gets imported into FSB. FSB data files count 0 KB data. I've changed FSB Data directory many times... MT4 history data location= C:\Program Files\FXCM MetaTrader 4\history\FXCM-USDDemo01.. FSB destination folder= C:\Program Files\Forex Strategy Builder\User Files\Data....I've pulled my hair out and now I'm bald!!!   Well...I may have been bald before, but...you get the point! Any help at all is appreciated ...thankyou in advance.
