MX Simulator

I tried to do the stock bike replacements and now everytime i try to connect to a server it says "mixed file mismatch" in the top left corner. What did i do wrong?

If you have the snapshot update installed, make sure you didn't forget to install the zzzrtestzx.saf file.

I have the exact problem and I do have the saf from the snapshot. It was working before I changed the stock models.
