Actually I tried that but they wouldn't launch so I had to go and redownload every single one of them but thanks for the post somebody put up about just clicking on the find sources buttons and it'd start downloading because before, I just assumed that the needs sources thing meant I had to wait and get it from a host and that seemed highly unlikely given the crappy downloading lately. I gave up until I read that post. now I have them all back, at least until the next time I upgrade or have to delete my preference folder or or uninstall/reinstall a version of LW.
