rs logix 5000 error message

I am getting the attached error message, I thought it was due to me copying the files over remote desk top but used a flash drive and still same error, reinstalled rs-logix 5000 still same error. I can open other files just not ones from this paticuler system, they will open on the server and work perfect. Any Ideas? And I dont have a service contract with Allen Bradley.

rs-logix error msg

I got this problem solved, at least for my application, I installed .NET framework 2.0 and then re-installed the rs-logix 5000 software and that did the trick, I uninstalled the rs-logix 5000 first, all the applications now work. Hope someone can learn from my experience!
