Wow...

Nobody is able to help me? I am surprised!

Another thing that I found out is that RealBand is also giving me problem whe I use the Tascam US-144 with its ASIO driver... I am able to hear the raw sound of the my guitar while recording quite clear but on replay it is very distorted!

If on the other hand I select the MME driver, I can hear the replay quite clear BUT... then I have no way of monitoring my live recording.
Also, when I use Guitar Rig 3, and try to alter its settings during replay, I get some warnings from windows allert boxes saying that there might be some problems doing the editing.

It seems that I cannot win either way!

Unfortunately it looke like that I will have to ask for my money back.
