Cant Upload my Map

So first off, my computer had to get a reset last year and logging in was fine back then before the reset. Now its just… frustrating. I put in my Email in right? enter my password then as soon as I reach to the “Select Character…” its just a black screen! I cant send a screenshot here sadly… Is it alright if somebody could help me?

there should be a drop down menu below the screen that says your name in it. Click “OK” and proceed.

Nvm, figured out how to solve the problem, Thank you!
