I am afraid I screwed up and do not know how to fix things.
I had Unreal Engine and all samples on my Cdrive but when the new update and samples were being downloaded yesterday my Cdrive ran out of room.
I moved the unreal engine file from Cdrive to a larger hard drive on the same computer and then deleted the file on the Cdrive.
I found the launcher application file on the larger he and it opened ok but asked about updating the uassets, I clicked ok but now the engine versions I had installed say repair instead of launch.
I clicked on repair but it does not do anything. I am new to all of this and on my own, please if you can help me I would appreciate it immensely. Thank you for your time with this issue.
