Gta V Says im not signed in

So my xbox is plugged into an extension cord. My brother stepped on it and flipped the switch off which turned off my xbox in the middle of a mission on gta v. Now whenever i load the game up it says i am not signed in(when i clearly am). I tried signing
in as every profile and that didn't work. I cleared the system cache and that didn't work. I deleted the install disk data and reinstalled and that didn't work. I tried turing the xbox on and off that didn't work. i tried cleaning the disk that didn't work.
Does anyone have a solution. The only thing i can think of is to buy the game digitally and hopefully have it work. But that is the final option after all else fails.

HEEEEELLLLP PLLLLZZZZZZZZZZZZZZZ!!!!!!!!!!!!!!!!!!!!!

Won't let me save, or sign in

I just got GTA v and it says I'm not signed in and will not let me save. I don't understand why. any help would be great. thanks.

 

Gta 5 says im not signed

Recently I also got signed out from Xboxlive and GTA online but that's probally because the internet cable I use from my Xbox360 to my modem is broken somewhere.

So if you've an extra cable, try that one.

 

As far as I know, this just happens randomly and it is an issue that will certainly fix itself.

Also, no-one uses the tags and no-one appreciates having that many down there. They won't do you any good, so don't bother with them.
