Diablo II trying to connect online stuck on "Checking Versions"

I want to start off by saying that I have owned Diablo 2 for years, yet have never really played the game, I think I tried playing offline a few times but wasn’t really into the game at the time, I just recently picked up D3 and have been having a blast and am now wanting to try Diablo 2 online but can’t connect… I’ve read this can be related to a ban but it would make no sense that I would be banned as I have never played online I probably don’t even have a total of 10 hours played… Anyways just wondering what could be causing this problem and how I can fix it, thanks.
