>[Fatal Error] main.pas(8): Unit acQBMOPgDACMetaProvider was compiled with a different version of PSQLDbTables.TPSQLDatabase

These errors mean that you have compiled the Metadata Provider unit with previous version of your data access components package, when you were installing the Active Query Builder last time.
Third-party metadata providers are always compiled during the Active Query Builder installation process (as we never know the exact version of third-party components installed on your PC), and if you upgrade the third-party component pack, you must also recompile the appropriate metadata provider package.
To do this, start the Active Query Builder setup program (click on the
"Start"->"Programs"->"ActiveDBSoft"->"Active Query Builder VCL Edition"->"Uninstall Active Query Builder" item) and choose "Add or Remove IDE Installations", click next, click on the Delphi 7 checkbox (the text "Action: Reinstall" will appear below the appropriate Delphi version item) and click "Next". You can tune the reinstall process at the next page. Click "Next", and the installer will recompile the selected packages using the currently installed third-party components.
If this won't help you, you must search the entire hard drive for *.dcp files from your data access components package and remove all of them. After that, recompile DAC and AQB packages.
