Looking for original MDA Compact IV touch sensor driver

[Neo Cortex]

Does anyone have the original MDA Compact IV touch sensor driver. I have installed Shaks custom rom on my MDA and it works perfectly except for the Home button. The key layout is different. See below

I thought that if I installed the original driver over the one in Shaks rom it might solve the problem. The file is called HTCNavi.dll
