You really have to learn to debug your triggers by yourself =)
When did the problem arise?
Did you create any new triggers before this problem came about?
Disable them and test.
Does it work?
If it does, fix that trigger or post the trigger up and let us have a go at it.
Nothing else I can suggest, though..
I used to get this error a lot.
But it had nothing to do with WC3, just my RAM. It went away randomly after a month or two.
