Hello. This is my first post. I am desperate. I have the a CASIO PX-575R. I previously installed the appropriate drivers and the keyboard was working fine. I've recorded with it multiple times, last using it Friday (7/20/18). I only started using it for MIDI about a month ago. I returned to record more Sunday and...nothing. FL Studio doesn't recognize it. My computer doesn't appear to recognize it. So I did the following things: Restarting my computer and FL Studio Uninstalled the drivers and reinstalled them Used a different MIDI cable Used another MIDI device with the same and different cables (worked fine) The keyboard turns on fine and works alone (it's a standalone keyboard with external power). It just stopped working as a MIDI device and now the computer doesn't recognize it. It also doesn't come up in the Device Manager. So tonight I tried to install the drivers on my girlfriend's computer and was given a message stating that would not install on this version of Windows. This is the same version as my computer - Windows 10. So look into it more and I find these: https://support.casio.com/en/support/osdevicePage.php?cid=008002002
https://support.casio.com/en/support/information.php?cid=008&pid=614 They appear to indicate that the drivers don't work with Windows 10. How!? It just worked last week! Anyways, I know I had a Windows update last week. Here is the website description for the update: https://support.microsoft.com/en-us/help/4338832/security-update-for-adobe-flash-player
I greatly, GREATLY appreciate any and all help. I've felt quite deflated. I don't know what's going on.
