LFG4 Freezes

[samsc]

I have two systems they are both exactly the same...
Mac Pro 8 core 4GB RAM, running CAT V4 PRO m119, PCI-e USB card with internal USB (to keep dongle safe) and LFG4....
I set up both systems exactly the same way using the slot expansion utility...
weird thing is both systems are running fine and all of a sudden one of them freezes the LFG capture. The other system runs perfect, never freezes...
what to do???

freezes all inputs at the same time?
after how long?

suggest you try swapping the card from one machine to the other - to see if the problem moves.
