Thanks for the patience you put to resolve this issue.
I downloaded the file you linked above.
It has not update the previous version, but installed a new version trial updated.
Upgrade7_6.txt log file say:
Quote: "Upgrade 7.62
============
Compiler
--------
* Recognise new BlitzTerrain module
* Recognise new DarkDynamix module"
When I tried to run PelicanDemo or Guess.dbpro, I got the same dialog than above but with different input:
Quote: "Failed to 'LoadProjectFile'
Failed to 'LoadDBA'
Failed to 'LoadDBA'"
There will be some witch on my computer that does not like DBAPro.
The problem is that to me if I like it.
