We have no access to your account or messages to see if eBay have notified you of any restrictions.
Or, is it because you have not successfully registered for eBay's Managed Payments ? Is there some information or ID eBay still require from you?
For this clarification you'll need to contact eBay Customer Services.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

Lines open between 8 a.m. to 10 p.m. on weekdays.
9 a.m. to 6 p.m. on weekends.
I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
