I lost 4 million xcn for that ridiculous backup function in qt. Software. I created the backup, and sure of what the software does, saved the file in two different places. Now that I go to use and import it back, it shows a .dat.url file which is a simple text about nonsense.
So you don't have a copy of your original wallet file or your private keys? If you didn't delete the data folder your wallet file should still be there.
I was on the run for a trip, just made the backup using the function button in the Qt. Software, and saved it in my flash card and my email (my wallet was encrypted of course). I just decided to delete the whole thing from my computer, and you know the end of my story..
I accept that I should have checked the files before archiving them, but on the hurry I somehow decided to trust the xcn software doing. My own fault, I admit, but my point for telling this story was to criticise the pace of progress.
I am glad that catia is back, and like you say, I hope that xcn gets the kind of progress pace that this promising coin deserves.
