Dunno if this is correct, not being a fedora/deadrat user, but just try the app's from the rpm's that you installed, if theyre corrupt, then they probably won't work.
Or just check where you downloaded the rpm's to i.e. /home/amOrpheus or /home/amOrpheus/tmp that should hold the actual rpm files - they don't just disappear when you click them to install.
Or you may be able to follow them via the package manager to see what/where the app's have gone to, and then uninstall them from there (this can be done from CLI, but I can't recall the commands)
If you can find the rpm's location as mentioned above, you could re-download them, and your system should probably tell you that file/rpm called XXXXX already exists, and do you want to overwrite them, if you're confident of the second download, then hit yes and overwrite them with the "good" files
