click & sound ahead of cursor

Hi there,.
I recently installed Cubase 5 - 32 bits over Win 7 - 64 bits. My interface is a Tascam 1641. Everything works fine, except sound and tempo click seems to be ahead (something like a quater note) of the cursor. It is also visible in terms of sounds graphics: sound is ahead orf the wave graphic.
I wonder if I should “calibrate” the tempo somehow, or if it is something wrong with my configuration.
Thanks and regards,.

Fixed this morning.

Problem was the interface, fixed with version 2.2 driver.

Thanks and regards
