A good place to start would be, as Gord Thompson has suggested, try and hold the SHIFT
key to bypass the startup form.
However this scenario suggests that the code might be corrupted. Sometimes, when you copy a file to a new location, the content of the file is disabled. So this could make the file in an openable state, where you would be able to Compact and Repair
.
If this did not work (copying the file to a new location), then the other option is to Decompile your file. So in the file location of copy you just made; create a shortcut. With the following as the Location of the item
"C:\Program Files (x86)\Microsoft Office\Office14\MSACCESS.EXE" "C:\PathToYourFile\YourFileName.accdb" /decompile
'Make sure the first path is the path where MSACCESS is installed.
'I have it in Program Files (x86).......
Then double click the Shortcut, you should (hopefully) have your file back up and running.
