Need Help have problems

Hello, I am working for a company that had been working with a
application made in GENEXUS, since 3 years ago.  We are migrating all
information from windows to Red Hat Linux, except the computers (3)
that we build the app's.  I have installed a Red Hat 7.3 server with
postgresql and transfered all my SQL2000 data files, this worked very
well.  I made a installation program from GENEXUS to installit in a
linux workstation with WINE.  Wine, worked very well, made the
installation correctly, but when i run the application allways appears
a "Runtime error 3683/6383 (i don't remember very well, i am at home but
i will send the error to someone that helps me)".  I configured my
workstation to use with TCP/IP on 5362 (i think this is the default),
the program recognize it by using ODBC, but when I login the app allways
appear that error.  GENEXUS generates Visual Basic program.

I really need help asap. I will appreciate all your help.   Thank You.
