Patching problems


New member
I'm trying to patch my Trainz 2010 from 42203 to 44088 but every time I run the patch, it comes up with this message:

This patch file is not applicable to your current installation version.
No valid patch operation was specified. Patching aborted.

I don't understand what this means.
Please can somebody help me get this patch to work?

Thank you :)
