I'd send Waves support an email and ask the question before uninstalling because what you have is at least working.
As for CPU/RAM issues I guess I'm a bit better set up with two PCs I use the laptop in the band room to get the raw tracks down and then do the heavy work at home on the big box, the only drawback is some of my plugins are only licenced on the big box so when we get together on Thursdays and the guys want a remix I have to make reams of notes and remix at home.
