First, Welcome to the forum!
Now...
If you're having problems with some of the TTS voices,
go to C:\Program Files\Haptek\player\data\HapTTS
and run the HapSAPISetup.exe file.
Characters...especially some that one might download:
make sure they are put into the characters folder and
that the extension is .htr NOT haptar.
Script files: be careful as there are still quite a lot
of script files that were written for Hal 5.0 and may
not perform properly with Hal 6.0 or 6.1 (most recent ver.)
Don't try to use all the plug-in files at once as there
may be some conflicts between them (not Hal's fault).
Some areas still need some work like a current help file
but a new release is promised this year that should help
address many user concerns.
Hal is a nice program that offers a lot of entertainment
and experimentation for the relatively small price.
The results you get depend largely upon how much time you
are willing / able to spend talking / typing with Hal.
The program will, in time, learn more about you and your
likes, behaviors, etc. and will begin to take on it's own
unique personality.
Please give the program a fair shake and don't expect too
much too soon...it does take some time.
As for problems, concerns, questions, use the search feature
at the top right or if no answer is found, post your
question here and someone should assist.
Sorry for your disappointment but try some of my suggestions
before giving up.
Good luck!
