Debug Assertion Failed ? -Please Help ! :(

[Sniper]

Hi, can someone help me please, my steam was totally fine last night until today, when my brother logged into his account and didn't log out, he said it was fine but now i just loaded up steam and it went straight onto his account and is coming up with this :

Debug Assertion Failed

Program: C:\Program Files\Valve\Steam\Steam.exe
File: Src\CacheFileFixedDirectory.cpp
Line: 1026

DirEntry.IsValid()

(Press Retry to debug the application - JIT debugging must be enabled)

then there are 3 buttons - Abort, Retry, Ignore

I pressed abort and it just quits steam and says the same thing again when i go to load it back up

I press Retry and it leaves it for 30 seconds then comes up with error message about having to close a program sorry for the inconvienience bla bla bla

I press Ignore and it comes up again and again

Someone please help, in all the 3 years ive had Steam this has never come up.
