On installing DAZ content:

You just run the .exe file, and the program, if it's never been run on the machine, asks you where to put the content. It may also ask you which version of Poser you have: there are signficant differences between Poser 4, Poser Pro Pack , and Poser 5 or later.

DAZ, while they don't want people to do repeated downloading, don't seem to have any limits on requesting resets. Better to keep well-organised back-ups, but they run a decent operation. They're not immune from doing dumb things, but who is?

Even slow broadband is hugely better than a dial-up modem. You can still make ordinary calls, and that big file will come chugging down the line. It beats an overnight phone-call for a download.
