MicroBoards CX-1 InkJet Printer

Have had this printer since August 2008.  It initially worked with litle issue, once I got it set up (not a simple matter of auto-install, I had to substitute a .dll file that a tech emailed me).  The publisher started acting up shortly after I installed the new Printwrite software, first with occasional coasters, then to outright failures on print jobs.  I had to send the printer back for repair.  Once I got it back and (once again) monkeyed with the installation, things worked fine for about 300-400 discs.  Now, the Printwrite software returns errors when I try to start it up.  The system/software seems awfully picky, and errors seem to often be of the major variety.
