Unable to allocate virtual machine memory!

Yesterday I installed Parallels. I put the two files in the shared folder and was able to run parallels in both of my user accounts. Today, I can run parallels in one user but in the other I get the following error messate
"Unable to allocate virtual machine memory!
This error may occur mostly if there is no enough free disk space available on the physical disk to allocate virtual machine paging file. Try to clean up the physical disk (remove unnecessary files). If it doesn't help, try to re-install Parallels Desktop."

I rebooted and downloaded and installed (repair) a fresh copy, to no avail.
Any clues?

Reduce the amount of RAM allocated to the VM.

For reasons I don't understand the optimum is somewhere around 800. On my machine (MacPro w 5GB RAM) if I allocated the max of 1500 I get the "unable to allocate" message every time. Around 1300 I get it sometimes, 1000 or less never.
Benchmarking shows there is no benefit allocating 1300 or 700.

I am sorry if this sounds rather arrogant, but did you try cleaning up your hard disk?

I tried increasing and decreasing to no avail. Reinstalling Windows worked.
 
Here is what I did.
I installed Parallels successfully in User 2.
I moved the files to the shared folder
I ran Parallels in User 1
The next day User 1 couldn't run Parallels
I reinstalled XP in User 1
I can't run it in User 2
