Problem adding databases and leagues

Hi.
I've done it before, but I seem to be struggling in getting my database changes and leagues to work. When I go to add the files, each one appears twice, or four times if I've saved them as a compressed file. If I add both of the files, it adds things like staff preferences twice. When it comes to leagues, it won't work, as I'm unable to add anything with a yellow ! on it. I've moved files here, there and everywhere, all to no avail. I did seem to have two locations for files at one stage too, some under public documents, and some under my user docs. All is now in one, under my user. Pleas help, this is driving me potty! All I want to do is manage the Curaçao national team, as edited by me! I have also tried using third party leagues, and had exactly the same problem. Any ideas?
