Reply to no response of the vci when i play jogeffects

IP Dual Core t3200 @ 2GHz
Traktor pro 1.2.7
VCI 1.4 powered by usb (power adaptor in course of delivery)
TSI 3.6.4
RAM 3 GB
Vista Edition Familiale Premium 32 bts sp2
HD REALTEK
ASIO Drivers
latency 11.5 ms

when i use jogeffects like a wild, the vci does not send any more answer. Leds are activated, traktor locks on the last sound and repeats, repeats...

to leave there, i control traktor with the mouse, i turn off/on my vci and it is OK.

please, how can i solve this problem ?
