Did you save any of the Projects as aia files and download them to your PC? If so, you can recover them that way.
Most probably they are deleted forever. Sorry.
What are the names of your projects... all of them. It might be possible, but to find out, it has to be reviewed by one of the technical
experts to see if anything is possible. Right now, most people here are taking a holiday weekend.
I am notifying the technical people of your problem.
Please tell us the names of your Projects. Someone will probably look, but you might not know until next week. If you need anything
immediately, you may have to re-code your projects. Otherwise, just use the aia files to restore them.
Regards,
Steve
