We had a price guarentee of support at $500/year guaranteed for 2 years. Our card was also stolen and replaced.
The two year price guarantee was an offer based on pre-paying the $1000 for two years by 12/1/2010. You had to proactively make the payment by that date. Did you do so? If so, you are all set. If not, then the increase is not related to the credit card issue, but rather your decision not to pay by that deadline.
