Hello: There are some instances where the processor and USB port on the PC is not compatible with the Book Port. Since we know it works on other computers, that is likely the case here. The only other thing I would suggest is if you have used other storage devices on the new computer, such as a digital camera--anything that shows up as a Removable Disk that would be assigned to f, g, etc., then you may need to reassign the drive letter to the Book Port. A good way to test this is to look in My Computer or Windows Explorer while the Book Port is connected and see if it shows up. If it doesn't, then you need to reassign the drive letter. If it does show up, disconnect the Book Port and see if the letter disappears. The directions for doing this are in the User's Manual. If it disappears when you disconnect it, and you haven't used any other devices that could be causing this, then you have an Incompatible Chip Set. The conflict usually occurs with AMD Athlon Chipsets. Since you have another PC to use, you may just want to go with that one. However, if you want the Book Port to work with this computer, then you'd need to go out and purchase a ADPCI card, which essentially gives you another USB Port. You would connect the Book Port directly into the port on the card.

When I had my other computer, I was able to connect my bookport to the pc, and everything was fine. However, when I got my new computer, and when I tried to connect my bookport to the pc, nothing would happen. I first thought something was wrong with the cable, but when I tried it on other things, it was fine. Is there anything else I should do? Thanks
