Ok excellent and great to hear thanks! Based on the number of downloads and the slowly climbing rating it appears there are still some GTA 4 folks around and they're liking the new AW. I'm glad I decided to ipck up the gauntlet again it's a fun project, especially when it mostly-works
I'm aware of the issue and as soon as I know the cause of it, and a way to fix it, it will be fixed.
If you still get that task related crash turn off UseTaskSequences in the Debug class and see. If it still happens or you see any other crash, make sure you are using a pure GTA 4 with absolutely nothing else at all edited, added, trainers, other ASI, nothing but pure GTA 4 and AW and see if there is any increase in stability.
