Set them modem to another COM port and point EFILive V4 to that port now. You're getting less info now because EFILive cant find the actual interface now instead of having the modem feed it bad data.
On my W7 laptop, I double clicked my modem in Device Manager to see how to change COM ports (havent done this for a while now, last time was probably 4+ years ago). So double click the ALDL cable, go to the advanced tab, and click Advanced Port Settings. Should be able to change the COM port there, then mirror whatever port you chose in EFILive V4. It might be slightly different to setup your ports, in fact its probably a little different.
