During upload or check-in, we receive the error "There is no Cache designated vault or active folder for Cache designated vault on Local Master Site

Has anybody ever had this message come up while uploading Pro/E data to the server:

"There is no Cache designated vault or active folder for Cache designated vault on Local Master Site"

Everything was running fine yesterday, but this morning everyone is getting this same message.

Any help would be appreciated.

Thanks.
