And how long is your path and file name?

The error message is pretty self explanatory:

An exception of type 'System.IO.PathTooLongException' occurred in mscorlib.dll but was not handled in user code
 
Additional information: The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

So use the debugger, find out exactly what your file and path names are. Then find a way to use shorter ones!
