Hello, when i try to launch FTB unleashed, the console says this,
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object. FTB Launcher was working until i updated it to 1.2.9. HELP, thanks
 
I am in a similar situation. I get the message
"java.lang.UnsupportedClassVersionError: Bad version number in .class file"
and then an error message appears and says "Could not find the main class. Program will exit".
This also occured after i updated to 1.2.9.

I have tried re-installing everything (including java) and it still isn't working
 
Antman, I have the exact same error. Mine started when I updated to 1.2.8.

I've re-installed Java, deleted old versions, reinstalled FTB...

Nothing works! :(

I also emailed the support team two days ago but have had no reply...
 
I've tried the basic troubleshooting but it still gives me the error "Could not find main class".

Is there anyway to download previous versions of the launcher?
