Can't checkout project from MS-Project Server 2013

Question

I got a problem with MS-Project Server 2013 and MS-Project 2013 (in a Win 8.1 PC). I can't checkout a project from the server. It says, that a "check-in" is in progress. My SysAdmin said, that on server side everything is ok, he thinks it could be a local problem with my pc.

Cold it be, that there is a tmp-file which causes trouble, if this is possible, where can I find all tmp-files for my local MS Project 2013.

Answer 1

I found a solution: Go to: File->Project Options -> Save --> „Clean up cache“.
