Error messages with cortex.

I have updated my cortex via internet and uploaded the 91 perf tune (advanced) to my car and then came back to my computer to get the Rotofab tunes and keep getting these error codes when I plug my tuner in.

First it states I has a USB port Time Out. So I waited and waited then finally unplugged and tried again and now it gives me these messages.

(2)A key exchange error has occurred

(M4) A read tuner data error has occurred

It keeps telling me to unplug and try again; I get the same messages.
After leaving it unplugged for longer than 5 min and try again, I get the USB port time out again and the same process starts over.

Any ideas?

Never mind, I closed the page and reopened it; everything worked.
