... tonight, I figure I will have to reload my apps and re do my settings etc etc. That's fine. But, what's the score with application activation on programs such as Quark and Photoshop? I have a huge project to finish this weekend and I don't want any problems i.e a demo version of Quark. Also, having never done an erase and install before, can anyone point me to a step-by-step guide? I have my PM to back up with (only the 'Book is getting tiger as it's mine - not the company's) but it's a minefield. I want to do a clean install as I'm convinced it will lead to less problems. Part of my brain still telling me to stay with 3.9 but sod it and I don't use iPhoto so who cares!!
