error:Default parameter specifiers are not permitted

Hello,I just added TurboActivate.cs to my project and tried to compile and got the following error:Error 1 Default parameter specifiers are not permitted ..., when I click on the error it takes me topublic static bool CheckAndSavePKey(string productKey, TA_Flags flags = TA_Flags.TA_USER) and underlinesthe equal sign between TA_Flags...This error shows up in all methods that use default parameters.My project is targeting .Net 3.5 (note: can't target 4.0-still using Visual studio 2008...).What should I do? Please advise, I need to get this done rapidly.

Unfortunately Visual Studio 2008 doesn't support "default parameters". So delete the "= TA_Flags.TA_USER" part of the function definition.

Thanks, that worked.
