Recently I bought a new laptop with Windows 8 on board. Then I downloaded and installed recent version (2.0.2.3) of AccessPORT Manager from COBB. Unfortunatelly included driver does not work with Windows 8, so APM can not connect to AccessPORT device. But there is solution described on COBB Tuning forum. You need to set option "Check for beta AceessPORT Manager" in APM Options. But it did not work for me, and when I looked to logs, there was a 404 error. Fortunatelly the second solution works, so I downloaded version 2.0.4.3 directly and installed on my Windows 8. Now I can connect to my AccessPORT and manage maps and logs.
