The first time I loaded up NetFlix instant streaming it worked great. Now its saying I have reached the limit of devices that can connect to the service. The thing is, I have only used my one Macbook Pro to connect. Under attached devices in Netflix its showing me as having multiple mac's with different serial numbers attached. Now its not even letting me deactivate any of the currently activated devices. So I guess my question is, is there a reason why their server would recognize my computer as having different serial numbers? Has anyone else had this problem and know of a way to fix it? Aside from having to call up netflix and talk with them about it, of course.
