I posted questions a week ago to the CCS Nav forum - no response. Sent personal message after that - no response. Finally said screw it, took a shot and tried to purchase your software hoping it would work. Got this error during purchase using a company credit card:

-----------------------
The following error occurred while processing your credit card information:
Error code:ErrorCode:15005 ErrorParameters:com.paypal.soap.api.ErrorParameterType LongMessage:This transaction cannot be processed. SeverityCode:1 ShortMessage:Processor Decline
!
Payment Response Ack: Failure / AvsCode: Y / CVV2Code: M

Please use the [Back] button of this form (do not use the [Back] button from your browser) to return to the previous page and make corrections before completing your order.
------------------------

Please contact me ASAP.

Sorry about the miss-communication. I saw your private message and started working on a new demo, but got side-tracked. I'll have a new demo online soon.

That error most likely means your credit card was denied.
It may be because your profile does not have your full billing address.
