It sounds like you missed a folder. Your path should look like this:
C:\Program Files\World of Warcraft\Interface\AddOns\CT_RaidAssist\files
C:\Program Files\World of Warcraft\Interface\AddOns\CT_RaidAssist\Images\files
Every addon you use has its own folder inside the AddOns folder.
Try making a CT_RaidAssist folder and moving things inside it.
/edit I have to go out for an hour or so, but try what I said, if it doesn't make sense or doesn't fix it for you, post again, either I'll reply when I get back or another of the fantastic community we have going here will likely step in and take over while I'm out.
