thanks,
Let me know if you need more help.
If you delete (or move/rename) the project's files, then attempt to access the project through the Start Page the IDE asks if you want to remove all references.
I have used this successfully in VB and VC# Express 2005 editions.
The easiest and most efficient way is to delete all the entries under
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\ProjectMRUList\
Deleting those entries is probably the simplest form for registery "hacking" you can do, and as long you don't do anything else this will not present any danger to your system.
There is no need to hack into the registry!
Simply delete or rename the project subdirectory then try to open the project from the start page. The IDE will tell you that it cannot find the project and ask if you want to remove references to it. Say 'yes' and it is done.
You can then rename the directory back if you want to.
