did you delete them or just move them?
if deleted, it's reinstall time...for every plugin that has rtas.
then rescan/redo any vst-rta, if you had it.
even with troublesome plugs either in dll or rsr/dpm, i move them to a place where it can't be accessed from the app and 'replaced by another version but never delete them. i'm reluctant to suggest doing a system restore, if it's even available and whether it would even recover deleted files, but there's things like undelete

as far as certain plugs not showing up, update the plugin. now if if it isn't fully legit, not sayin' it isn't, and i know many who get the legit and then use the 'other' version to avoid using dongles and such, there's another solution that's been floatin' around the net, especially if dealing with old versions and/or legit but abandoned ware plugs that never got updated
a note on waves: only the waveshells go into your dae/plugin folder, if they aren't there in both dpm and rsr then you didn't install the rtas. time for the ever pleasant reinstall and make sure it's pointed to the right folder
