When you say "can no longer run it"... what happens?
- the sln files are not compatible; you'll need different sln files for each VS version
- the csproj are mostly compatible, although you might see a "version 4 not recognised, using 3.5 instead" warning or two, which is usually fine
- the cs is compatible as long as you don't use
dynamicor the other new language features
In most cases you can get away with just having a separate sln for VS2010. So just rename it to "Whatever_2010.sln", get your old "Whatever.sln" back from your source repository, and rename it to "Whatever_2008.sln".

If you want to get rid of the "tools version 4.0 not recognized" warning, you can just look for it in the .csproj files and change the "4.0" to a "3.5" by hand. – Joel in Gö Jan 19 '11 at 14:27

after changing Tools Version to 3.5. Visual Studio 2010 asks me to upgrade your project.. After upgrading it replaces this 3.5 with 4.0 – Mohsan Mar 10 '11 at 05:58
