I am having a issue of DevicePakg for 4507R-E not present in RME 4.1.1,i tried uninstalling all cat4000ios packg from RME repository & then update RME again with Cat4000IOS.RME41.v5-1.zip & it all dependencies but it failed, so i uninstalled all the packg in RME & when i try to update them all again it doesnt happen, now i uninstalled RME4.1.1 application itself, i am unable to install it again.What to do now ? I have earlier installed lms 3.0 & then updated devices packg, then decem2007 software updates for all application.Please suggest how can i fix rme again.
