Incorrect details error

Hey guys!
New here today, just wondering if anyone can help with a little issue.
I've had a huge batch of problems downloading all the relevant stuff, every type of torrent software etc. just not working, couldn't access the first link for the download so had to use the GoogleDrive one.. Messy.
Anyway, it's all done now and extracted, and I've changed the realmlist and a 1.12.1 client is running - so far so good. However, when I try to log in, it gives me the usual blizzard message of incorrect details etc. Now, I know the server is only just not officially released, but I wanted to test out if the download had all worked. I was wondering if this was the correct error to receive? It seems odd that it wouldn't be a "server not up yet" message, although if everyone gets this then I can feel a bit more at ease.
Thanks in advance!
