Hello!
I looked at your account, you really have some files for which downloads have not been paid.
This is not because they pay only for some countries, but because the system did not recognize the download of the file to the end, that is, the full 100%.
There may be several reasons for this:
1. The user downloading has installed third-party programs or applications that prevent the transfer of his cookies.
2. The user is using a VPN or anonymizer.
3. The connection was interrupted, the user decided not to wait for the download of the file or problems with the Internet access.
