Problem with corrupted file after saving.

[fluhunt62]

Hi everyone,
I'm experiencing a frustrating issue with SoftMaker Office PlanMaker. I've been working on a rather large spreadsheet for the past few days, saving it regularly. However, today when I tried to open the file, PlanMaker reported that it was corrupted and couldn't be opened.
I've tried opening the file on different computers and with different versions of PlanMaker, but I'm getting the same error. I'm worried about losing all the data I've entered.
Has anyone else encountered this problem before? Is there anything I can do to recover the file or prevent this from happening again? I'd greatly appreciate any suggestions or advice.
Thanks in advance!

Have you checked your backup copies? Unless you changed it, PlanMaker should save backup copies of several previous versions of your file when you save.
