I was using prepar3d v3.1 and moved back to v2.5 because the pmdg 777 would always get errors over long flights and when I used v2.5 it worked better. Question is I installed v2.5 and it won't show the 737 or the 777 installed in the Operations Center

I was using prepar3d v3.1 and moved back to v2.5 because the pmdg 777 would always get errors over long flights and when I used v2.5 it worked better. Question is I installed v2.5 and it won't show the 737 or the 777 installed in the Operations Center

 

Did you reinstall pmdg product you probably have to do that and uninstall it from add remove programs first
