Sounds more like a corrupt or missing file to me.
Yes I know, I think it is probably one of those two files, I heard of something like that happening before but I cant find the thread. I've been searching for it but you know how that is...
OK it is on mql5.com thats why I couldnt find it, compiler error
I have reintalled the MetaTrader, but until now still not ok.
Any body can help me ?
When you reinstalled it, did you uninstall it first ? If you didn't the installer might not overwrite files that are the same version. I would suggest install a new instance of Mt4 in a separate new folder, call it MT4_2 or something like that and see if the same issue occurs with a completely new install. Also install it from the link at the bottom of this page, not from a broker website.
