I don't really know why it's not working for you. You're the first person that couldn't get it going.
Do you have access to Control Panel on your device? If so, have a look in the Input Panel section after running my scripts and see if you can see SkyDemon listed in there.
It is much more likely that the problem is with the scripts than the SIP itself. You could try a completely manual install of it:-
1) Copy skysip.dll or skysip480.dll into your windows folder
2) Copy regsrvce.exe from
here into your windows folder
3) Browse to your windows folder and double tap regsvrce
4) Click 'browse', then browse to your windows folder and double tap the skysip.dll file
5) You should get a message saying DLL Registration Succeded
6) Go into control panel > input panel (or click the icon at the bottom right by the clock) and see again if you can activate the SkyDemon SIP
If it is the scripts that are broken, and the manual install worked OK, then I'd still like to work out why so I can fix the scripts.
Failing all that, if you want to send me your unit or meet up somewhere, I'm sure we can sort it out.
