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 dynamic or 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".
