As there were few different complaints about problems with some files, if you have any problems, please, try to use same files from different source.
Meaning, not only different source in 'separate links by countries', but also from different '[Only registered and activated users can see links. ]' source.
Not every single file can be tested on every possible bug, and some of them are from same basic source, it is always possible that some file is corrupted from one and not from other source.
