Hi A Jarrett,
Thanks for your reply.
I sugegst you will need to check if if
these files can be created in VS2013. 
Since the VS2008 is really old version, and generally we open an old project with the closed VS version, for example, I sugegst you could check whether you could open all files in VS2010, and then test it with VS2013.
In addition, I suggest you can try to open the your project solution using File | Open Project... and then pass the path to the solution project file check this issue again.
I find a similar thread about how to convert project from old version VS to VS2013, you can try the jsck's suggestion to check your issue.
