The following process has crashed: UE4-myproject

I can not open the level or levels in recent and not in ’ open level ’ ’ What could be happening ? I can not open a new level , but can not open I had saved. I’m working on a home project with many 3D models. I’m with little memory play games in HD then withdrew the models of PC and put on a thumb drive , do not know if there’s something there … I need help , I am not studying because of this. PC configurations: Win 8.1 version 4.7 EU4 4 GB RAM 500 HD In the limited 15 GB FREE Video card nVIDIA Geforce 730 Zotac 2GB Pentium dual core Can anyone help ?

It looks like that project is corrupted. If new projects you create do the same thing, I recommend reinstalling UE4
