I've used Keepass to store my strong passwords for a couple of years, with my back-up on dropbox. I installed Windows 10 (dual boot with 8.1) this weekend. Don't know if it's related, but now Keepass won't open my database because it's now saved as a kdbx.tmp file rather than just kdbx. Both on my computer and dropbox online. I could sure use all my passwords.
Any ideas how to remedy this?
