Hello-- A couple of weeks ago, an IDE error caused some minor damage to my Data.fs file. Unfortunately, there had been some significant changes to that file since the previous weekly backup, so I did not want to restore from backup. I used the fsrecover.py utility to recover the damaged Data.fs with great results. A few folders inside Data.fs did have problems, but all of them were corrected by exporting and importing the damaged folder and just re-importing it . . . except for one. With this one folder, I get a POSKeyError. After researching this problem online, I used the fsrefs.py utility to determine which object it is that's not being found, but I can't figure out how to either a) get that object back (since I can't access the management screens due to the error) or b) remove the invalid references. I have seen some references to truncating (a copy of) the Data.fs just before the transaction that causes the error, but I haven't found any instructions on how to do this. So, is there any good way to fix this by either replacing the object or deleting the invalid transaction? Thanks, Jeremy. -- Jeremy M.
