apparently I did but maybe I can fix it. I tried to copy my TiBu folder back onto my phone and it says it can't do it. I have mtp selected. The thing is nothing has ever been backed up on the phone as it is now, and the TiBu folder is not a folder, but a file. But it seems to read as a folder so I can't make a new one, and I can't copy anything into the non folder. I'm scared to death to remove that folder/file thing so I think I will back up a single app and maybe that will turn the file into a folder.
eta: the backups are on the sd card which I can't seem to access via my pc so I'm hoping to put them in a new folder, then copy/paste them into the TiBu folder.
eta: that worked-I was able to move the files, then when I refreshed the apps list in TiBu it showed all the old apps. I'm restoring now and crossing all fingers and toes that it works.
