My Studio won't work

(I have already made this question a few days ago, but I did NOT get a good answer and it did not help me at all, so I am asking this again, in hoping that this will get the answer that I am needing):

Well, I guess this isn't really help with scripting, but I've asked everywhere else, and I've gotten no good answers.

Okay, so, whenever I go to Develop and try to edit a game, it takes me to a different world that is definitely not mine, that has no bricks in it, whatsoever. I even try opening the studio directly and try logging in, but it won't even let me. It won't even let me switch to classic view to log in. And yes, I've tried completely uninstalling, and re-installing both the Roblox Player and the Studio multiple times.

Please help. It's been like this for days. (Well, actually over a week, now.)

Windows: This may be a firewall blocking your places from studio, virus, or just a weird glitch. Check to see if there is any other firewalls. If that dosen't work, I suggest uninstalling both client and studio, restarting your computer, then redownloading. If none of the things above worked, email info@roblox.com

Mac: Don't know, don't care. Sorry.

Hmm I'll try. I had this problem so I know what to do. Have you ever tried going into Studio and going see classic mode? That might work then copy the URL link in Studio then put it in your explore.. It SHOULD work. Comment if not.
