Query: exchanging mine

My experience with this product was less than satisfactory. I installed it on an XP machine according to the instructions. It led to error messages and the creation of an LPT3 port which was "unusable". It did create COM4 and COM5 which is what I would have expected.However, my machine came to a grinding halt, would hand indefinitely on startup.I did a system restored and reinstalled the PCI board. Same thing.Perhaps I got a lemon so I will exchange it. Clearly the other reviewers here had a more positive experience.
