Logicport owners help - driver issue

Logicport has stopped working in the lab, and now when we start the software it reports -

"The LogicPort hardware may already be in
use by another instance of the software".

It appears to be a software glitch that causes these problems. Our prof is considering sending it back to Intronix for repairs but we are losing time on finishing our project. (It appears that the usb interface using FTDI/eeprom chip on logicport is poorly designed and may need reflashing! FTDI drivers apparently had some major flaws then ) Can someone please let us know if you have seen this issue come up before? Intronix, the maker of Logicport, appears to be a small company (it appears one product only) and does not have a forum to share user problems with their product

Update of our problem: The problem started after the Logicport was connected to a computer running Windows 7. Earlier, with Windows XP it was running fine. The FTDI chip on it 245BL with a separate eeprom. The analyzer enumerates when connected to a PC, the yellow LED remains turned on, but when we run the software it does not recognize the hardware and the message is "The LogicPort hardware may already be in use ...... " (shown in the previous email above).
