Server causing my Client to Crash

So far I've tried using the DynIp and the default one but to no avail it didn't work and I've also tried reinstalling forge and the mod on my pc to try and fix the problem but it always crashes with a "Error: java.lang.IndexOutOfBoundsException" which sends me back into the Client Screen.

Also the mod was 1.7.10 Orespawn that required Forge 1.7.10-10.13.2.1230 and as far as I could tell the mod doesn't have a PTRLib file

Sry to have no responded for so long but regarding the issue I just deleted a file in .minecraft called "options" and I could log back in.
