RealPort: I can't open com port

I installed RealPort in order to send modbus requests from my computer to my ConnectPort X8 Gateway. I tried the communication with Hyperterminal openning the virtual COM port that i’ve created, but i got this message “COM12 can’t be open. Check port settings” (but this message in my language. I translated it). I tried install and removing driver, rebooting my PC and rebooting my ConnectPort, but I haven’t got success. I see the virtual COM port in the Windows’s Device Manager, and this is available in the Hyperterminal, but it can’t be opened.
Does RealPort is right? What should I do in order to use it?
