Often have to reinstall dolphin?

[2step4nathan]

I'm on windows 7 ultimate x86, and I was just wondering if anyone else has this problem, after one or two uses I need to download dolphin again and extract it somewhere because the client won't work, it'll start the program but it won't let me see it or use it or anything. I've tried the SVN, and the thing won't open with the microsoft visual studio, I'm wondering if there's a fix to this or anything because I have trouble reloading my save games when I need a new copy of the emulator.
