Hello. First, sorry to write in English but I don't understand German, and there no possibility to use French. So It may occur some mistakes of translation. I would like to use LogView - V2.75 with my computer (Windows 8) and a Graupner Ultramat 16 S. While logging LogView a message appars telling ther is : no port selected the comport is not available no device selected On the Device dialogue the part dedicated to USB is not active (only RS232) I did plug the CPX 210 ... restarted my computer ... no more result. Thank you for an answer, in English please, to help me to solve this problem. Bye.
