Auto update Zmodeler 2.1 to 2.2 won’t response on my computer.

Hello,
Today I’ve auto updated Zmodeler 2.1 to 2.2 and it won’t response on my computer and then I am getting an error message. And I’m unable to move back to 2.1 since the 2.2 is the updated version. So now I'm fixed with a broken Zmod. The earlier versions responded fine except for the version 2.2.
Just now I updated my XP Pro from Service Pack 2 to Service Pack 3.
I'm running a registered Zmodeler more than a year without any problem. How can I update it to version 2.2, if not how can I move back to the my previous version? I hope there is someone who can help me to resolve this?
This is the error message I found while trying to open Zmod2.2
J:InstallationsZmod2Zmodeler2.exe This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.
Thank you for reply.
