There is an update to the MQL code for exporting Expert Advisors. The update fixes a compilation error in the newest MT5 - 'NormalizeComponentValue' - function already defined and has different type.
The MQL code will be updated automatically at the next start of FSB Pro.
You may force the update by deleting the content of the C:\Program Files\Forex Strategy Builder Pro\User Files\MT4 Files\MQL folder. If you decide to do that, you have to re-install the custom indicators you use.
The MQL code v49 will be silently introduced in the FSB Pro v3.8.8 installation package.
