EPDM Cannot Read or Write the Contents of the File

Hello Everyone,

I am having trouble transferring some SolidWorks files into our vault. When I drag and drop a file into the vault I get the error:

"SolidWorks Enterprise PDM cannot read or write the contents of the file 'C:\...." This can happen if the file is corrupt or if it is a newer version than SolidWorks Enterprise PDM can handle. Do you want to proceed anyways?"

I am running Enterprise 2013 SP1, and SolidWorks 2012 SP4.0.

I have tried to save as a different file name, check to see if the file is read only, etc. As far as I can tell the file is not corrupt.

Had anyone had a similar problem and how did they fit it?

Thanks
