Can't program CJ4 FMC after SU4 and wt mod

I installed SU4 and the working title update. I can’t program the FMC as before. It seems like the working title mod is not installed. After turning on the master battery and avionics, the idx button on the FMC is not functional hence, I cannot begin programming the FMC. Need help.

You may have to turn the avionics switch to dispatch.

Oops I just read you have avionics on. That should do it.

return to main menu and try again… till idx button works

Thanks for the replies. I’ve been to the main menu many times and tried over and over to no avail. I also removed the ASOBO CJ4 and the wt mod’ reinstalled both and tried again. Nothing seems to work.

did you also update the G1000 from wt ?

No, didn’t know it was required, too.

I thought I should confess: it was my fault. I put the entire unzipped folder in the community folder instead of the file inside the folder.
