No, I packed it in a zip-file, but I used LZMA as method, so, I don't know why, it gives an error
Now, with Bzip2, it should work (tested ;)).
About the level up-/downloading:
I'll create an external program (in c-skript), who uploads all levels on the server and then downloads all from the server. So I can use GSHTTP
But I must know, which user I must give the rights on the server to create textfiles. Can anyone help me?
