Ok just like the guy below me I am having issues getting the interface to work. I do not have the disc. I downloaded the unsigned version due to the .net 2.0 issue. I downloaded and extracted the drivers for windows 7. Usually the first time I try the drivers I get a blue screen and have to restart my computer. It shows one mpvi and one unknown device. Device manager shows 2 mpvi's I do the update drivers to each. Then it shows channel a and channel b but gives an error 52 that the drivers arent signed and are faulty. Anyone have any ideas I have taken pictures of the device manager as well as a video from start to finish of everything I have done less actually downloading the software. I have to have this running by Friday. Please help.
