New VDK-80 version 1.7

Mike Gore has identified a major bug in the code of VDK-80, which caused several files to be completely ignored by the program because of a wrong logic implemented in the handling of the Hash Index Table. Therefore, this latest update presents a significant improvement in the way files are located in several different DOSĀ“s. I can already imagine all those people lining up to get this new version as soon as possible! :p Thank you, Mike!
