looks like Poco Mail crashed but I didn't notice

Anyway. What happens is athis.
I can open Poco mail, send and receive mails etc. Everything looks ok
BUT
I cannot put a new contact in the contact list
I get "Access violation at address 009F6581 in module Poco.exe Read of address 000010"
AND
I can open the contact list but it is empty.
If I begin writing an address say, under "to:", Poco completes the address
Example I enter "r" and Poco proposes "rabanito@xz.com"
Any tips? What could I do?
Thanks in advance
