I may be out a limb here but…

 From the ‘bad file number’, I suspect you are using the DF1.  If its the same file you are using with the development version, then I would not know …. if its a different file, is there any upgrading and data checks that need to be done on the DF1.

and….  $construct+0006 in the drop list ….    what is at line 6?    a DML command?    file open or closed?   Connected to a database or not?

I get this error when opening up a window in Studio - Error when executing method at J2Inv/convcode_droplist/$construct+0006.  Unexpected error, bad file number passed to data manager.  Any major changes in dropdown list from 6 to 10?  I do not get this error with the development version.
