Help my Modpack doesn't work :(

[Charismara]

My modpack doesn't working. It starts loading it, then crashes. In the technic launcher console, it shows two lines of error Messages:

[20:02:42] [main/ERROR] [FML/]: There is a binary discrepency between the expected input class a (a) and the actual class. Checksum on disk is 9af4586e, in patch 1121659. Things are probably about to go very wrong. Did you put something into the jar file?
[20:02:42] [main/ERROR] [FML/]: The game is going to exit, because this is a critical error, and it is very improbable that the modded game will work, please obtain clean jar files.

I have installed the following mods for MC 1.8:

Battle Tower

Your pack launches for me. Try deleting and re-installing.

Your pack metadata indicates that you are on version 1.0. This is often an indicator that you aren't incrementing the pack version number when you change the pack data/metadata. Always increment the pack version number any time you change the contents of your modpack archive, the location (URL) of that archive, or any data specific to the pack on your pack settings pages.
