I noticed that autodetect game paths is turned off. Are you having an issue with detecting the game paths? Also is this a standard CD installation or is it Direct2Disk or Steam?
Here is a version with debug logging turned on in the areas you are seeing a problem. Install 2.16 with the installer and then unzip this over the top. You can preserve your config file since there are no configuration changes from 2.16 to 2.17.
TQVault 2.17 BETA3 - Test
You should not have to even load a character. Just load TQVault and mouse over something in your main vault and let the error show. Once the error shows close TQVault. Just do it once since alot of information gets written. Also, let me know what the item was and if it's not part of the all artifacts vault please send the vault to me.
