Hello, I recently upgraded to Windows 7 (Pro 64 bit) and so far it's all been running smoothly. However, when I installed the 360 SDK (7645.1) I found I wasn't able to connect to my XDK. I was previously running XP (Pro 32 bit) where I was able to connect to the unit fine (although the connection would sometimes drop out while I was transferring files to or from the unit). I'm able to ping the unit just fine. I also created an XP virtual machine and installed the SDK on that and still wasn't able to access the unit. I suspect this is an Xbox failure, but I'm hoping it's just a software issue. Any help would be appreciated Thanks, -lucas93
