Moveable Type login and .db filesd

From scouring the forums, I know there are more than enough Moveable Type issues to go around. But I couldn’t find anything that related to the problem I’m having.

I was using MT on my old host, and when I installed all the files on my DreamHost directory, I could no longer log in. MT suggested updating the DB files, and gave very detailed instructions for doing so. The contingency is to contact the server administrator.

I wasn’t able to do anything, and now I’m really confused.

What needs to happen? I’m not sure if this is a problem I’m supposed to be able to solve or if the solution needs to come from the server end.

Can anybody help? And is there anything else I’m going to need to know to get MT working?
