Vista stopped working

Tue Jun 12 02:41:02 2007

I had been using REALVNC on vista.  It was painfully
slow so I applied the vnc-mirror-1_7-x86_win32.exe
patch.  It worked wonderfully.  I paid for my license
key which worked for a few weeks and now states that
my license key is expired.   I can re-enter it and it
accepts it as a valid key but it still does not work. 
Since I paid for it and expect some mininal level of
support and which I have never recieved I am assuming
they went out of business for theft.  That being said
I still cannot get REALVNC to work.  I'm connecting
from a XP laptop to a VISTA desktop.  I've uninstalled
and reinstalled, tried it without the mirror patch all
to no avail.  Does anyone have any idea what to do
next?  

Thanks
