its quite strange that ppl found via driver is unstable ??
i have used various agd gears on different computers for past few years and never had any trouble no matter what it is, jriver, foobar or playing youtube via chrome :|
if you follow exactly instruction then there should not be any trouble?
regard driver installation i always put the driver installation folder into main drive c:\ and you must not delete it after installing driver, also need to go to via panel controller to activate the asio driver for the 1st time then every thing should be ok.
