Environment Windows 8.1 enterprise edition x64 (6.3 Build 9600 WinNT) + Visual Studio 2008 pro V9.0.21022.8 RTM

Why Visual Assist X, in the above I will appear all sorts of strange problem??????? Have tried at least five versions of VAX (1709, 2358, 1903, 2393, 1738, etc.)!!!!!! Reshipment restart countless times!
Problem a: code coloring failure (in a text editor is a failure, at least in the listbox appears to work, but I don't need) every version of this problem when I tried, I also the most unbearable thing,
Problem two: function parameter information blocking the current input line (also exist in every version I tried),
Point three: lenovo's name list box is blocking the current input line (only 10.5.1709 does not exist in my version of the attempt to this problem,)

To solve the three problems,,, I do not know why this time came out so many moth! In w7 before and w10 hat vs2008 VAX never met these problems...
Does it really to VAX and Win8.1 had been enemies...
W7 and w10 interface gave me a whole aesthetic fatigue, really don't want to change the system

The great spirit of all stripes for help
