Going to play offline as 'nikilase'...

Everything works now after just deleting every version and downloading them again.

My log in button is grayed out to. How do I re download versions?

@Donna W:
Please do the following:

  • Reinstall Minecraft

  • Start the launcher

  • Wait until "Loading Versions"

  • Attach the complete output of the development console. CTRL-A, CTRL-C there, CTRL-V in the ticket.

I completely deleted all files in my .minecraft folder and reinstalled. This did not help.

Progress!!! I now see this. However I still cannot click any tabs or interact with the drop down boxes.

Why does it work a bit / What did you do ?

I really didn't do anything different. When I launched the game a new update for the launcher was downloaded. I couldn't do anything again. So after several attempts of shutting it down and restarting, I replaced the newly downloaded version of the launcher_profiles.json with my back-up version (the version I copied from another PC that I successfully logged in with). This time when I restarted I was presented with graphics (minecraft brown background) and an box I could interact with. It asked for my email and password. I entered this info and it gave me the gui you see in the screenshot above.

As I said before I still can't use the drop-down box or click the tabs etc.

Version 'XXXX' is already tracked problem is fixed.
