CorelDRAW X5 :: Crashes When Run PowerTRACE?

I keep having the experience that when I run PowerTRACE it says the bitmap is too large and must be reduced to trace. If I click cancel, X5 crashes immediately. If I click reduce it works sometimes and crashes sometimes. I tried tracing some of the same bitmaps in X3 and they worked fine. Is there something I need to change to allow PowerTRACE in X5 to run more smoothly? Is there a way to up the memory allotted to the program?

I'm running XP SP3 with an Intel Core 2 E8400 processor and 4gb of ram (3 of which XP actually knows how to use.) Not the most spectacular setup but it worked fine with X3. I tried adjusting the quality vs. performance option in the PowerTRACE settings but I can tell any difference.
