The FTB Forum is now read-only, and is here as an archive.
To participate in our community discussions, please join our Discord! https://ftb.team/discord
Since you have not given us much to work with I suggest following the steps here first to ensure that the ftb launcher is installed in the recommended way. Please read the "Other useful Information" section for some additional help if needed.
If you are still having issues then go here for help with obtaining and posting logs.
