To make things immediately clear, I'm using DP on a single computer either. So, when I'm using DP on a computer the other one is shut off. I did this second upgrade/installation for security reasons.
After having upgraded DP7 to 7.24 and rebuilt permissions when I loaded DP a dialog box told me that the authorization file was incorrectly installed - so I wasn't able to open old and new files at all.

So with Find any File I succeeded locating the hidden authorization file and deleted it
![Wink :wink:](./images/smilies/icon_wink.gif)
Then I uninstalled both DP7 and 7.24 rebuilt permissions again, reinstalled, authorized DP7 and upgraded to DP7.22.
Actually the program is stable and working but I don't feel safe upgrading again to 7.24 because I fear to go back to that aforementioned annoying situation.
So, is capable DP 7.22 to read (and save) 7.24 ones? Will I have to retain the same DP releases to work without hassles?
At present I'm stuck at 7.22.
Please help if you can
TIA
