More Elven Legacy

OK this game is starting to annoy me -- not the gameplay, which is very tight and terribly addicting but the missions are SADISTICALLY hard. I had to go to Easy and I have been playing games like this for a long, long time. Just wave after wave of bad guys.

And it crashes -- a lot.

As in, I can't play for more than 60-90 mins without getting some sort of "stack delay" CTD error or something like that.

edit: it just crashed again:

Call Stack Functions:" and then lists some letters and numbers and the path to the exe file.
Anyone have a clue what that means?
