You are opening for the first time, but I'm not
Recently I have been getting this message sporadically with some applications after a restart. Parallels even asks to be re activated sometimes. Also, more often than not after a restart my Safari home page has defaulted back to the apple web site.
I have done a complete reinstall of the OS from the retail SL disk and run the software updater. I have repaired permissions and verified the disk. Lastly I have dumped the com.apple.luanchservice.plst and cache.
Please... any other suggestions. Its a macbook pro.
