Visual studio 2008 problem

i am using visual studio team system 2008 and VSS 2005. I took a latest copy of a project from VSS. Now when i try to open that project, it is showing error

"This version of visual studio does not support source control"

and

" Unexpected error enocountered. Restart the application Error : no such interfaces are supported File : vsee\internal\vscomptr.inl".

When i open solution explorer, all projects are showing as unavailable. I tried

VS-->Tools-->options--> source control-->plugin selection

and set plug in to Microsoft "Visual source safe" and when i open "Environment" tab it is showing

"an error occured while loading this property page"

Can someone help me???

Got it...... Yipppieeeeee http://support.microsoft.com/kb/952102

VSS? Just say no. Not helpful, I know.

I'd start with deleting all the VSS files in the project folder, opening the project inside VS 2008, and then rebinding.
