Project Crashes when opening in engine 4.5.1

Hi, I dragged a material onto an asset, the engine crashed. Now when I attempt to open my project I get a crash report everytime. This is crash report:

MachineId:5D55F1E2499C7CF77E14909DE03FDAE1

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

Please help me restore my project, I’ve spent forever on it.

Many thanks

Hey Ben -

To restore your project, from Windows Explorer go into your project folder and copy the mesh asset ([NameofYourMesh].uasset from the Content folder to the Desktop. This will cause an error as the engine cannot find the mesh but the engine should now open your project. If however it still crashes, try also removing the material *.uasset you assigned to the now removed mesh asset. If this restores your project, can you upload a copy of the mesh and material *.uasset and any texture *.uasset needed for the material for us to test?

Thank You
