A sync error ocured. press stop and play to clear

[erolz]

Hi,

Just installed a clean Cubase4 with all the latest updates (4.52).
When i load the Virus TI Snow as VST instrument and start playing my song (with or without any sound loaded in the TI) the Virus control software keeps saying "A sync error ocured. press stop and play to clear".
When i press stop and play the (empty or with midi data) song again, it keeps on saying A sync error ocured. press stop and play to clear...
I wont stop.

Heres my setup:
Intel DualCore2 2GB RAM
RME FireFace 400 connected to a TI fw chipset
Virus TI Snow connected to USB
Steinberg Cubase 4.52
Virus TI Installer 2.7.5 for Windows

Anyone here got the same problem?
Thank you.
