i dont think names and names of files are here allowed ,...

but yes it is possible that people block some countrys , there are blocklists for country's , so certain clients from certain country;s can almost not connect .

i dont know if this is the case for you , most of the time this is done not because they are greedy , just because of some safety or a thaugt of safety....

but in your case : have you check the file with bitzi ? so it is not an fake file ?
