At the moment, people might not realize what is happening in case their network connections are slow, or in case something were to break during downloading.
Adding more textual output when delayed actions are occuring would probably also help.
Perhaps the CompressedFileWrapper struct should be extended to store any compression error information, in case a download gets corrupted. That way the user can be told the reason for the file download failure in a more suitable manner, and not just a case of it disappearing with the text "Decompression failed!".
