Hello everyone,
My friend found a FTB Unleashed 1.1.3 Server and i tried to join it after installing "ForgeMultipart-universal-1.5.2-1.0.0.121.jar" and "IC2NuclearControl-1.6.2.zip" which was required by the server. I also deleted the old versions of these two mods. Then I tried to connect to the server but I got that ID Mismatch error. You can find the screenshot of the error. I also tried to totally delete FTB and re-download it but I did get the same exect error once more. If someone helps me I would be so happy.
