All the EAs I have on Metatrader 4 used to work, it would trigger trades and alerts. Ever since my demo account expired, 99% of the EAs no longer does work like they used to. I also had tried reinstalling MT4, but no such luck. Any ideas?

BTW, I know someone will ask if I have the "SMILEY" face, yes, its smiling.
Expert Advisors is on, Allow Live Trading, blah, blah....

It was yesterday in the morning for me: some unknown data with unusual stop loss and everything was mixed and nothing was closed. I did a call (phone) to Alpari and they said that they had error in data server during the half a day. It was fixed by itself in the evening.

The only problem is that mine has been like this for over a week now. I guess I will remove demo completely, install demo, and copy all EAs and indicators again, just hope I do not have to recompile anything to get this working else it will be a nightmare.

I had similar issue after I installed build200, the spread became 6 from 0 for EUR/USD, this caused my EA(which check spread) not entering any trade, I modified EA and it worked.
