Hi,
I have the same problem. Stupidly long loading times, my project need about 35 Minutes to load because between every instance of EWQL there's a gap of one minute where just nothing happens.
I also got the crash dumps message, but they are ok. As long as you do NOT press the OK button everything just keeps working fine. If you pree OK, then Vienna will crash and force you to go through this long long loading process again. :)
Did you contact the EWQL support yet?
I did and they promised me an update, but that was last december. Perhaps the more people write to the support, the sooner we'll get an update :)
