Impossible to confirm my order - help

Hi

I want to confirm my order in order to add a new tablet I just bought. Unfortunately when I connect to my account and either reject my order, because the one listed is too old (01-13 while I subscribed new one in 01-15), or accept I have the following message : 

Update you page or try lately

Error id : 6037a140-443a-44de-8fc5-3fd7403719b9

We are sorry but you cannot acceed to the page you tried to show. Try to update the page. If it doesnt work please retry later.

It is what I do since few days but I still not succeed. Then help me!!!!
