If you have downloaded this 3th party GUI (http://www.md5decrypter.co.uk/hashcat-gui.aspx ) from md5decrypter.co.uk you should ask for help there http://forum.md5decrypter.co.uk/forum8-g...ssion.aspx , right ?
Gui is not supported here, because it is a 3th party software (from md5decrypter.co.uk)
And, other versions of GUI (http://hashcat.net/hashcat-gui/ ) listed here are outdated, therefore either you choose the way to use the md5decrypter.co.uk gui *OR* (recommended) learn to use shell/dos commands and use oclHashcat w/ CLI (command line interface).
