Well you aren't the only one using D.O.G.'s importing feature. I always use the DFend feature to create very large test sets, +20000 profiles.
I had almost a few 100 people using the feature.
Also asking for support and getting it for free software is always better then not getting any at all for paid for software.
There were some very minor problems with the scaler option of DFend prof files of other languaged systems, "the 1.0 or 1,0 problem", this one is now fixed.
Also the import dialogs got a small visual update, it now shows all problems with the DFend import feature.
All these things would never have been part of D.O.G. 1.54 if somebody pointed me to the problem they were having. If you check DFends history, if you still can find it, Mabus also had a lot of bugs over the years. Some of wich he would never had fixed if they were not reported by his users.
And also D.O.G. and DBGL are not even a year old, so expect some minor issues.
I would recommend to try D.O.G. 1.54 again.
