Repeated conversion of Web project file

I had the dubious honour of converting a VB Web app from Visual Studio 1.1 to VS 2008.

Every time I opened the converted (or so I thought) project, it gave the following message:

The following Web projects must be converted to the new Web Site format. The conversion process will remove all source control bindings and the project will not be under source control after migration.

After the 3rd attempt it was not funny, so I googled it and found this fix:

1. For the project that's causing you the issue, backup your solution file, your project file, and the "hint" file associated with your project file (the .vspscc file sitting in the same directory as your project) to some other location.
2. Check out your solution file and the project file and close VS
3. Open the project hint file (.vspscc) in notepad, change the ENLISTMENT_CHOICE from COMPULSORY to "ENLISTMENT_CHOICE" = "NEVER"
4. Open your solution file in notepad, remove that line SccProjectEnlistmentChoiceX = 2 (X is the number that corresponds to your project that is causing you the problem). Also, if you see the line "SccWebProjectX=true" (x is again the number of the project in your solution), remove that as well.
5. Open everything in VS again, and assuming everything works now, check in your files.
