Dymo Labelwriter 330 stopped working and will not reinstall

Dymo Labelwriter 330 was working when last used 10 days or so ago. When I tried to print address label today, printjob just went to queue and showed as stopped (found this out when there was no label printed and I clicked on Dymo icon in Dock). I could not restart print so I deleted instead and reprinted with same stopped result. Used System Preferences - Print & Fax to uninstall Dymo. I downloaded latest driver from Dymo.com Mac_DLS771.dmg and installed. Went back to Print & Fax, choose More Printers to re-install Dymo; box comes up searching for installed printer drivers, followed by larger box that shows Dymo Labelwriter in slot with drop down arrow on right side and then all closes back to Print & Fax in 1-2 seconds with out giving choice of printer or chance to select/click anything. Running OSX 10.5.2 with all available updates installed. How do I get Dymo Labelwriter 330 installed and working again?
