Yes, your Forge installation is corrupted. So you don't need to delete your whole MC installation, just the installation of forge you have. To do this, go into your .minecraft and go into "versions". Inside versions, there should be a folder with 1.7.10 and forge in the name. Delete that folder, and then re-install the most recent recommended version of forge for Minecraft 1.7.10. That should fix your issues.
