I asked GoDaddy support to hurry it up if possible, and (at my surprise) they finished it in only few hours (as opposed to 1-3days).
Anyways, I created a new MySQL database, uploaded the rocketlauncher contents and I'm currently installing it to my server. Everything seems to work so far, I have successfully installed the whole package now i will delete the installation directory.
So, I guess the problem is solved, I wish to create 'Guide on installing Rocketlauncher on GoDaddy server' thread, where should I post it?
