Pioneer CDJ Connecting Error to Cross 3.2.0

Hello Guys,
During the weekend I had a gig and I have installed Cross 3.2.0 version, so during sound check I plugged 2 Pioneer CDJs to my PC and I opened the software, I pressed link on the CDJ in order to set Cross settings, both screens on CDJs displayed connecting, and they never connected, I restarted my PC several times and I checked the Software version of both CDJs and it was up to date!!
Any idea how can I solve this issue ?
Thanks a lot..
Chris
