Because of delaytime in ProE while swtiching the windows I tried to install an older driver. (version 2.1.2) But... this version is not suitable for ProE.
After removal from that driver, I installed the 3.1.3 beta-driver. This one did not worked, so I removed it, and installed driver 3.0.9.
After installing the new drivers I cannot use the device. It recognises that I am working in ProE (showing on the spacepilot-display) but only the Esc, shift, Ctrl and Alt key is working.
(Strange thing: I removed all drivers and software, but still the display shows the buttons I have programmed before removing all drivers.)
What can I do to get it working again?
