Archive isn’t opened

When I packed archive with various data I rechecked all files on viruses, all files were pure. But couple of days ago the archive refused to open and it reported: Unknown method in filename. I tried to open it by means of other programs for archives, but unsuccessfully. I have no notion of how to repair winrar archive.

This is a little vague. can you give us more to go on?

Pretty sure due to his join and post count that this is just another one of the random spammers the forums have been getting lately.

Sure is a weird way to spam though.
