So I should note I'm on a IBM Thinkpad T23 with XP Pro SP3 installed. I use the serial port and do not use any USB adapter or PCMCIA card to connect to the AEM EMS.
With the new version of AEMTuner 0.86 I could not connect to the car so I ran the USB lib file provided and still cannot connect. I get the error listed in the other thread which is here:

AEMPro of course works just fine still, but this version of AEMTuner does not connect. Something is not working with this USBlib file it seems and it is causing newer Vista machines to have more serious issues it looks like from what Spaghetti was saying and also the OP of this thread.
EDIT: The program (AEMTuner) does not freeze up nor does it do anything besides pop up this window. It will not connect, but I can still modify tables and all the other normal stuff besides connecting. It happens every time regardless of changes in setup (connect on program startup, connect by selecting connect from the drop down, etc...). I do not have freezing issues, nor have I noticed any issues with my USB ports or audio.
