why do the EAs run on Interbank metartrader but not the metaquotes metatrader?

 
hello I have a new problem and its driving me crazy. I've developed some EA's on the interbank version of metatrader, and they work fine on that platform, but when I try to run them on the metaquotes metatrader, nothing happens. No trades are opened at all, no matter which expert I run. I've gotten all the 1 minute historical data back to 1999.
 
I figured it out, after several hours. It's the huge log file created from the optimizer. Mine was around 140 mb. Apparantly it gets so big that nothing more can be written and so you have to delete it and restart metatrader. The fix for now is just to clear out your journals each time after you optimize an EA.
