CC payment info being declined...

I am a new site recently started. Just opened it up after testing Credit card transfers and they were all successful.

I now have had several customers try to order and their cards are coming back declined. I then tried it myself with my personal card and It also declined me.

Here is the error I get from the "Decline":
SGS-002000: ERR 26 - CALL SUPPORT
1262962966

My site is http://(remove)gunshowgoods.com/zencart

I am also getting confirmation emails from a successful transaction that is actually failing.

Any help or suggestions would be highly appreciated. I am very frustrated at this point and not sure what else I can do.

What CC module are you using?

First Data linkpoint...

Have you contacted them? Have you asked your host if they have made any changes? Have you added or changed anything on the site recently?

I have a ticket placed with first Data.

I am receiving a "Decline" error for every transaction placed on my site.

Thanks,
No reply as of yet.

I haven't asked the hosting company if anything has changed because they are to notify me of any changes. What would I ask them if I were to place a ticket with them?

Only thing I changed in the site was to turn off the linkpoint payment module so people didnt use it.

I found the same error referenced in this thread: http://www.zen-cart.com/forum/showthread.php?t=47644&highlight=SGS-002000%3A+ERR

Don't know if that will help or not.
