My 1 password 3 application has disappeared. I was trying to troubleshoot a red exclamation mark that had appeared in my online list. My passwords wouldn't work. The trouble shooting page told me that I needed to reinstall the extension, which I did. Then it said that the extension couldn't find the helper and I should open my desktop application to go to the menu. But my desktop application would not open. So I followed an instruction on the forum to throw the application in the trash, empty the trash, and then re-boot the computer. But I was afraid I would lose all my data, so I threw an alias of the application in the trash as an experiment and rebooted my computer. Then I could open the desktop icon BUT it was a totally different interface. It gives me two choices: new data file or Find existing data. I clicked on Find existing data. My download file opened. I could find only one file for 1 password and it was grayed out and I couldn't select it! Meantime, the icon on the safari bar had disappeared and I feared I had lost all my data. However, I tried Firefox and found the icon there. I opened it and saw my passwords were still there but was afraid to experiment any farther. Please Help!!! I have already spent hours and hours on this and am at a deadened!. This all came about as a result of unsuccessfully trying to download 1 Password to my iPad using Dropbox.
