So is the module showing up in modules or not, in your post you said one time it was showing up, and other time you said it wasnt. Looks to be problems with your LiveChatPro module? Unless it uses an override, you can probably just delete it from your module folder, and call it even. If you really wanted to delete db stuff, then look for anything livechatpro and delete it, backing up your db first of course, incase something goes wrong.
