I have upgraded my cute editor version from 5.3 to 6.5(.NET 2.0)

I have done the following 

1. Deleted and re-refered the new dlls and lic file

2. replaced the CuteEditor_Client folder with the new ones.

 

Now i am not able to see anything in the editor part.Just a white box

I can see one javasript error "Objects doesn't support this property or method"

i debugged the script and found that the error is in  "window.CuteEditorInitialize" function.Please help me to resolve this.
