Error on project startup

While working, for some reason my project crashed and closed. Since then every time I start it it get an error with this text. Not sure if you can make anything out of it, but there it is.


We apologize for the inconvenience.
Please send this crash report to help improve our software.

Also while running thru the last log I found this part:

[2015.03.01-12.08.20:888][ 0]LogWindows: === Critical error: ===
Fatal error: [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.6\Engine\Source\Runtime\Core\Private\HAL\FileManagerGeneric.cpp] [Line: 613]

I was using the ver.4.6.1 of the engine.
Would be glad for some help.

Ok nevermind. Managed to fix this by removing the file mentioned in the log.
