RU12 and CUBASE LE7 - Audio drops..

I am having difficulties with RU12 and Cubase LE7 (AI Elements)
the audio i have recorded is not running smoothly and have drops every few seconds…

My OS is windows 7 Ultimate.
computer is AMD Athlon X 4 750 Quad core 3.4 GH
with 4G RAMS and 64 bit operating system.

the RU12 is new and i have registered the hardware and installed the latest drivers…

is something to do with drivers? license? computer specifications?
Anyone can help here?
