That sounds kind of weird. I've just checked my library (I don't really use it though), and I cannot get the program to not show the left column.
If the program doesn't start either sometimes, it sounds more like a general pc problem. If you uninstall the program, there still may be some registry entries holding some settings for the library. Ooops. I just checked my registry, and actually, there are tons of sony entries. The only sony stuff I have on the pc is the library.
I'm not sure if it works, but maybe uninstall everything again, and then run cccleaner (or so) to clean up the registry. After that, just to make sure, restart your pc and reinstall the newest version of library again.
I've run through several such issues with other stuff like labview and new hardware or different windows versions at work. It's a pain in the neck, but usually I got it to work (sooner, mostly later).
Good luck
