[Help] Anyone have a way to get it to work with Windows 8.1?

Does anyone know? PLEASE!

The client just keeps crashing.

What client?
There are literally thousands of different game clients...

I believe its the client version 3135

That version number means nothing...
KPT. JPT, BPT, EPT, CPT, PTP, VPT, or one of the millions of other private pt server versions...?

Oh I'm using MPT v3135
I used this guide to set it up

Have you try to execute the game in compatibility mode of windows 7?
