help with purchase!

[Puma Man]

I was ordering a set of ProMedia 2.1 speakers through this website when I get to the credit card info part of the ordering. In bold red letters it says:

After pressing the purchase button below your credit card will be charged. If you receive an error do not go back and press the purchase button again. Please call customer service at: 1-888-554-5665.

So I enter all the info, and when I click "Purchase" I get this error message:

We are sorry, but we are unable to process your request:

Changes to the data require your review. Please review and resubmit.

Please go back and correct the error and try again.

I don't know which one to listen to. Should I go back and re-enter the info and press Purchase again? Or should I leave it at that and hope that the speakers arrive some day? Also, after I got that error message and pressed the back button, the shipping cost went from $16 to a mere $4.

PLEASE HELP, because I am just leaving the browser open until I get further instructions.
