Having trouble with UPS and PowerStore 3

Hi:

I'm having trubble with UPS and powerstore3
.
When I turn on shipping the transaction fials and I get this responce. "Transaction Not Completed" we're sorry Your transaction could not be compleated. Either your credit card information or billing address has problems and cannot be processed.Please return to checkout and try again.
If I turn off shipping thr transaction goes through (kind of ), but the next screen has No Paypal Express checkout Info, Shipping info and it ask for New account info. When I try it as a regestered user I the screen "Transaction failed" your Paypal transaction could not be completed. Please return to checkout and try again.
I'm sending some screen shots,I hope they help. I'm not sure of the code used for finding out the exact error. PayPal worked when I first set it up, but after setting up shipping it stopped working to I guess.
The first scerrn shot is when the UPS failed, The seconed is showing the page with no PayPal Express info or shipping info.
I do have to say you guy at webassist have wonderfull products, always a little tweeking to get it to work for the differnt sites, differnt hosts. But you have always got them working for me.

Thanks in advance for your help
