Yah Justin, everything will still be installed. Just run the install program. It will even still show your recent uploads.
BUT:
uhm...Trylon....someone? Suddenly I can't UV map anymore...not sure why. it was working just fine BEFORE I updated. But for some reason, after I unmap my faces, after I call up my image I'm not seeing it in the 3D windows. And I've GOT to! Else I can't adjust the mapping to make the texture look right on the object.
What did I do? Feels like I turned something off. I mean, this is a new object I just created after the 2.45 update. A cube no less.
EDIT: Later. Never mind! Never mind! I figured it out. Back on the tutorials, there was a warning about needing to have the texture in the same directory where your blend file is stored. Well, with 2.45 something changed. Before I didn't have to do that, now I do. Once I put the texture in with the same folder as my blend folder, poof, it showed up in the 3D window.
Grrrr.....stupid Blender....making Andy feel stupid......
