Por tools LE 7.0 wont launch

Hi- I have Pro Tools LE 7.0 running on my HP XW8200, I have not installed any of the updates and it has run very well for the last 2 years. I went to use it today for the first time in about 2 months and it will not launch. The mouse pointer turns into an hour glass for about 7 seconds, then it goes away and the program doesn't launch with no error message. I had the training version of Avid DS software on the same system, but I uninstalled it, thinking that it might have something to do with it but it still wont launch. Any thoughts? Thanks; Brian

I would try putting the install disk in and running a repair.

Thanks, I ended up restoring an Acronis archive of my c drive and that did the trick. Thanks for your response.

You get a gold star(head) on your fridge for having a backup plan:D:D:D:D
