This problem is really annoying me quite much and I have no idea how it happened.

I got a Wacom Bamboo Fun Tablet for Christmas 2009, and was using it with my old computer.
When I got a new PC last year I plugged my Tablet into the computers and windows installed its drivers and I installed its additional included drivers through its installation CD.
For months, everything was working fine and I got these additional cool features, such as an effect every time I tap or double tap on the screen (A little circle would go outwards from the pointer), get to draw on Stickies, which is handy for me as it is like a checklist, and the handwriting feature on Messenger 2010 would detect pressure, meaning the harder I press, the thicker the line is and vice versa.

All these features seemed to disappear after I changed one setting; disabling the 'Hold to Right Click' features as it was disallowing me to draw smoothly on my painting software and I already have a button for that on my pen. Then, the features stated just disappeared and I have no idea what caused them.
I have tried re-enabling the hold to right click feature and re-plugging in the device numerous times with no luck.

I don't know whether this is a hardware issue or caused by a Windows Update. The tablet still works fine with the computer, just all the things are gone.
What should I do?

PS: I went into Task manager to find 2 process under the name 'wisptis.exe', described as "Microsoft Pen And Touch Input Component". There should only be one running, and one is using more memory than the other.
This is ... weird.
No way!
