I have converted many small personal projects and a few large office projects. When the conversion begins and starts to hang, notice that your CPU is still being used. The conversion process simply takes time. Start the process before you go to bed or leave the office.

You will also notice the program not responding in the task manager, this is normal and if you sit and watch long enough it will switch between being responsive and not.

If it really does crash (not just hang for a long time), then you might need to enable the 3GB switch.
