Yeah, that's perfectly fine. I may or may not be around, but if I'm not, we can always put it off for a few days. Chances are things will be fine, it's just that it isn't viable in the long run for you to be using a system that is, for all intents and purposes, relatively crippled in some fundamental way.
Take your time and let us know when you want to continue. You're right; it is possible that with the SP2 update we could run into the same old problems. But we also may not. It's a bit of a stretch, but there is a remote possibility it could actually solve nearly all of these problems all on its own, as it replaces a great deal of system files and re-registers them.
Also, to everyone else here at G2G, I am hardly a perfect tech. As such, I'm open to ANY advice or input you've got on this issue. If anyone disagrees or thinks there may be a better way to approach this, please do speak up.
