Query: Stopped working after a couple of uses

I had an older cell phone with infrared, so I bought this infrared adapter when I got a new laptop with only blue tooth capabilities. Similar to what I had read in some reluctant reviews of this product, it took 15-20 minutes to install the software and get my computer to recognize the port (I have a Sony Vaio SZ740 with Vista and MS Professional).I was able to use the device a few times before it quit working for me. I could see in Explorer (Windows button + E) it was there, but my control panel infrared icon no longer recognized the adapter. Luckily I recently got a new phone with blue tooth and a micro SD card. I wouldn't recommend this adapter to a friend--I was hoping for a fairly cheap way to link my phone, but ended up with more headaches than it was worth.
