AQB Soft replied to me in chat saying to use the update process in market.  That does not work as it does not show an update. Perhaps AQB can give us the update script and we can upload the files and run the script. The main module on my site is the Articles module and it is also not working and throwing db error. It is version 4.0.0 and 5.0.1 is available in market but not in update. Frustrating!

Hello. All released update scripts are available for manual downloading on this site -> product page -> Download subpage. You are welcome to download and install them manually. If you have the license for the app you should have the access to the Download subpage.
