I dont know why this is. I'm using the newer version that says SBX pro studio on it with sound blaster in the top left corner, sb1095. it came with the newest creative drivers on the disc, so it must be at least from last year. pretty unsatisfied with the tone of the thing in general and wanted to give PAX drivers a try to see if I could either get more configuration options (speaker distance?) or even just some tweaks in the way the device sounds? but like I said, I downloaded three different 2015 file packages from the server, and none of them work -- PAX x-fi 5.1 pro 2015 1.00(17mb), x-fi 5.1-pro 1. 00(17mb) and x-fi 2015 1.00 (200~mb). Am I missing something? do I have to install an older version first or something? something else I have to do first? is there a reason it isnt detecting my x-fi? Its plugged in right now!
