Under 9.1B05, _qbuild.r did not need a database connected to run. Since compiling with the posse 1.0 release, _qbuild now requires a connected database.
To fix this issue, replace the _qbuild.r file in adeuib.pl with the _qbuild.r file in gui\backup\adeuib.pl
e.g.
cd "c:\program files\progress\gui\backup"
mkdir adeuib
prolib adeuib.pl -extract adeuib/_qbuild.r
prolib ..\adeuib.pl -replace adeuib/_qbuild.r
