Oh this?! ( .dft file not opening)

[bazzy]

I went to get back an old design (but not so much, the last access is May) and it doesn't open it anymore!!! at startup gives me this error:

"Impossible to open the file. make sure that the file is type and version datti for the application and that it disposes of reading privileges"

? ? ?

in revision manager the apre, I tried to copy it but nothing.. .
Could be an open file with st and by mistake slated v20!?
(because if I use it only me and that I have been careful not to ever save with st I pore quite strange though)

in the past it happened to me, and it was corrupted files and then to remake or recover from backup, but it was the time of v14, obviously admitting that you didn't make any mistakes to the rescue (salve in st format and then want to open it with v20, the reverse doesn't create any problems).
