I am unable to open one major table in an Access file that I had no problem with on 3/29. When I try to open the table I receive the error message: "The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time." When I click OK I receive the message "Microsoft Office Access can't open the table in the Datasheet view." I can open all other tables in the file without a problem. The file is on a local machine and is not on a server, so no one else can possibly have access to this file. The only thing I can recall that might have caused this is that on 3/29 when this file was open my computer froze when trying to shut down, so I had do to a hard shut down that day. This is a critical table and I don't have an older back-up of the file. Thanks for helping to open thistable.
