First - Timeout Error Second - Computer Froze Third - connection to server not reache

[Pundgy]

Alright, so last night when I tried logging in, i'd type in my server name and password, then wait a couple seconds and get a timout error. Thismorning I tried again thinking there might be something going on with the server, and the computer would freeze. Now this afternoon, i'm trying, and it's telling me no connection to the server could be reached. I'm pretty computer illiterate, and looked for other similar threads, but i'm not sure if my problem's the same as many mentioned, and I don't want to tamper with files and mess something up even more. Anyone have an idea why this is happening?

Thanks in advance
