Thanks for the clarification!
The tech that came out suggested a new card. He did nothing more than pull the card and put it back in the chassis. On Friday, he said his contact at NEC would locate a card for us and ship it out. Today he says we should just buy one ourselves. I don't have a lot of faith in this guy.
So, while I am comfortable performing the steps you outlined below, I do not have the Cos-session software. In addition, are there any reputable re-sellers you can recommend to get a card?
Thanks.
