Soooooo about a year ago I was really into the classic minecraft version and I played actively on 2 servers that are no longer up, which is fine. One both of them I made a large Disneyland that took me 4 weeks to build. Actually, it probably took me longer, I can't exactly remember. Fortunately I saved it, so I have it on file. I tried to make my own server, but my computer was too horrible to run it. Other people could go on it, but I couldn't. So now I've been planning to get back into it, to continue my Disneyland expansions. But now it wont let me onto World of Minecraft. It says, "Unable to Authenticate". I tried to go onto the normal browser, and every time I try and enter a server it says, "Failed to connect, or the server is down!" Something along those lines. 

I'm lost here. What's going on? It's making me really sad cause all I want to do is play it again. I'm not good with computer stuff. I don't really understand any of this. I remember a while ago people were having problems with World of Minecraft, does it not work anymore? I don't know what to do..
