Wow, looks like its one of those days.

I forgot to include the folder uc_linkpoint_api in the ubercart update. When I realized it was missing, I put it in the shipping folder instead of the payment folder. Because of this, a required certificate file needed to connect to linkpoint was not found, and I kept receiving the error:

Sorry - Could not connect to payment gateway.

All is well now. Thanks for the quick update Ryan, eliminating any possible ubercart changes helped me narrow down my search so much quicker.
