OK, it was totally my fault for not backing up the darned thing and being complacent about leaving it in the default location. So I think when I updated to the latest version of 1Password, I lost my data file. But, when I retrieved the folder from the trash, the data file WAS NOT THERE. Or so it seems. There is no file with the appropriate name/file extension ANYWHERE on my computer.
I've searched on 1Password, on Agile, on .agilekeychain, and I've found nothing. I am out of ideas. And I have not emptied the trash. (Actually, I immediately pulled everything out of the trash and stashed it in a folder for now.)
Am I totally, um, up a creek here? I shudder to think that I will have to rebuild the entire database manually, especially as I have been depending on it instead of my memory for logins, tracking license codes, etc. Thankfully, it's not grown beyond software and email and website ID stuff.
So, what do I do next?
