Problem z nakupom na internetni strani

Pozdravljeni,
ko hočem potrditi nakup na eni strani se mi izpiše naslednji tekst:
Server Error in '/payex2' Application.

Runtime Error

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Naprej še nekaj piše ampak mi ne dovoli kopiranja, ker vsebuje Web. confgig. Kaj narediti? Hvala

...
nič ne moreš
napaka na njihovi strani
