Try re-setting your Visual Studio settings. Go to Start > Visual Studio Command Prompt (2008) and run the commands sequentially:
尝试重新设置 Visual Studio 设置。转到开始 > Visual Studio 命令提示符 (2008) 并按顺序运行命令：
devenv /ResetSettings
devenv /ResetSkipPKGS
See if this does the trick...
看看这是否有用...

I had a similar issue once and I just did a complete repair of VS. Have you tried that? Not an uninstall/reinstall, but a repair?
