Ok, so, stupid mistake. I was looking for Particle Forge, which I didn't realize had to be downloaded separately. I thought it might be on the disk, so I inserted the disk and clicked the option that said "Modify Available Options". I thought it was just scanning my files until I realized how long it was taking. Then I read the fine print that said "installing", and I immediately cancelled it. After that, I started up Sins, and noticed it still said v. 1.09 in the corner. So far, it all seems fine other than the fact that I'm missing my update history in Impulse. My point is, is it all still 1.09 or did I mess things up and now need to reinstall everything?
