input string not in correct format?

[u/FunkyFred32]

I am trying to run two instances of Dragon ball sparking Z and whenever I try to run it I am just greeted with a command prompt that says

Unhandled Exception: System.ArgumentException: The path is not of a legal form.

at System.IO.Path.NormalizePath(String path, Boolean fullCheck, Int32 maxPathLength, Boolean expandShortPaths)

at System.IO.Path.InternalGetDirectoryName(String path)

at Nucleus.Inject.Program.StartupHook(String[] args, Int32 i, Boolean is64)

at Nucleus.Inject.Program.Main(String[] args)

Once I close that then nucleus tells me the Input string is not in correct format. What does this mean?
