@Rowtax1 Thanks.  Yes we pretty much operate the same way with copying ATB file year after year.  When one of my files crashed for the first time last week, I did just what you did: take the last year and roll it forward again and relink.  And then after relinking, I did not click the automatic import box.  Will have to hold off until the glitch is patched before I check that box again.

One way we have salvaged a corrupted file is by having our IT person copy that uncorrupted file from before the time window that these crashes started happening and send it to us.  From that point, take that file (example YOURCLIENTNAME.22C)  and drag it to your desktop and then change the file name by adding something extra at the end before the file extension.   Then go back to the proseries and then under Client maintenance, click Restore and find that renamed file and restore it to your client base.  That should result now in having a duplicate client file.  We kept the corrupted file because it already has the Efile status and acknowledgements (not sure if really matters because hell will freeze over before any of those files open up, but it gives our managing partners peace and tranquility). 

Now, before you open the new second file, you have to go to where you keep your ATB copies and take the file that is usually imported from and make a copy of the folder containing all of the nuts and bolts.  Make sure that you change the new folder name to something else after you make the copy.  Once you have done that, you can delete the original ATB folder that you made the copy of.   By doing this, you have essentially severed the link that the automatic reimport function triggers every time the file is opened. 

Ok, now you may open the new proseries file you just restored and you will be greeted by a different, but proper, error message this time saying the Trial Balance import could not be located.  However, the file will open and you'll have access once again!  I'd recommend immediately to uncheck the automatic import function at this point.  Final step is that you may now rename your copied ATB folder back to whatever your usual naming convention was.  You'll have to wait until proseries updates the software for the glitch to relink.

I know this seemed like a tall order, anyone can easily just do what you and I did in the first paragraph, but this was very helpful for jobs that were materially finished, including fixed asset manager imports, manual state return adjustments, depreciation adjustments (including those pesky section 179 manual state overrides) the list goes on.

Anyone else who reads this and tries it, let me know if you managed to salvage your files.

thanks.
