My TB profile is on my home NAS, which has worked fine until I installed TB 102 (64-bit). Now when I enter my account password and check the Save Password box, login to the account fails and the password is not saved. I can access my accounts if I don't check the Save Password box. I've tried deleting the key4.db and cert9.db files. While they are recreated, it doesn't fix the problem. There are no file called "logins*" in the profile directory, which I've seen mentioned in previous discussions of this type of problem. I used Sysinternals PROCMON to try and get some idea what's going on; i.e., what files are referenced when saving passwords. I did notice repeated attempts to read key4.db at offset 24 , length 16 which always failed with NETWORK_ERROR. Other accesses to key4.db succeeded. I have programming experience and am willing to use the Debugger under Developer Tools. I just have no idea what to look for. Thnk you for any suggestions you can provide.
