Problems with 2 TIs on FLStudio

[Cenobita]

Hi guys,

I´m trying to open 2 instances of Virus Control on FLStudio (one for my Snow and another for my TI Keyboard), but I´m getting this message:

"Virus unavailable

Another application is blocking your connected Virus devices. You need to quit it first before Virus Control can connect and use it"

Since there are 2 different plugins for each device and they are connected to different USB ports it shouldn't be happening, am I right?

I'm running FLStudio 10.0.9 on a Dell Inspiron 14R i5 ivy bridge (6GB ram), my synths are connected on USB3 ports (one of them is powered but in a hub (motherboard) and the other is "dedicated". Tried use them with and without connecting my tascam US800, but it doesn't make any difference.

It doesn't seems to be an USB issue, since, on FLStudio, VC recognize the Virus I power up first (at any USB port) but when a open a second instance, that message above appears.

I did read and followed the FLStudio setup tutorial, but it's outdated, so some parameters do not exist anymore and I left the "new ones" as default.

I reinstaled the VC with no success and even tried to use VST2 and VST3 plugins together, one for each virus...

Does anyone have a clue of what I am doing wrong?

PS: sorry for my rusty English...
