DOW shouldn't give an access violation. If it does then reinstall Wine - POL is just a front-end, the problem lies with how Wine is installed. I've played Soulstorm, DOW II, Gothic Armada, using POL - no problems with any of them either on install or when running them.
As for the other applications, try searching the net for "Wine access violation" to see what results you get.
