i have a c2d mbp with parallels running off boot camp and last week it was running perfectly. started up fine, coherence was working great, no problems. then this week i can't seem to get parallels to boot up winxp at all. it starts to load and then gets stuck on the Microsoft Windows XP screen with the blue bars beneath it. the bars just stop. any idea what can be wrong? i can still boot into winxp with boot camp, i've tried removing the VM, uninstalling parallels and reinstalling, no luck. thanks.
