Vvvvbeta20 osc and start

I have being using vvvv beta12 for few years.
NOw I downloaded beta20 and I `m having strange problems:
1- With beta 12 I was receiving data via osc from eyesweb with no problem.
If I open the same patch with beta20 Data arrive not continuosly, but like blinking.
2- If I close beta 20 for two times, the third time I try to open vvvv just nothing happen. I have to restart my computer to meke it work-


I really don `t have a clue about what could be the problem.

( I have windows vista on a dell inspiron 6400 )
