When i start Forge in my minecraft launcher it goes well at first but then after a while when it starts it just shuts down and says " It looks like you are using an unsupported modified version of the game" and "The game crashed whilst initializing game" and it just won't work. I have checked so that i have uptdate 1.12.2 on forge,minecraft and all the mods (4) i downloaded so i don't know what could be wrong! Here is the error thingy:  Error: java.lang.NoClassDefFoundError: com/mia/craftstudio/IPackReaderCallback

Do you have DecoCraft2 installed? And do you have PTRLib installed with it?

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

what is PTRLib?

It's a library which is required to be installed for DecoCraft to run. Try installing it, a quick search online revealed the same issue with PTRLib missing.
