It would be useful to know if an error is returned when you try reading, and what the dialogue box at the bottom of the Modem Configuration screen in XCTU shows when this is attempted.
natanel, Do you have a firewall enabled? If so, you may need to either disable it configure it to allow the X-CTU software to download updates.
Before you do anything, may I suggest checking to see if your X-CTU software has the necessary firmware files installed on the PC. You can do this by selecting the proper modem type and function set. Then check the version tab for the 2x41 version you are looking for.
If you do not have it, the it may become necessary to download the necessary files from the support site either with the X-CTU software or directly.
