Thanks, Raptor...

But i was able to resolve my problem with the changes in the file in question.
This is what i did to change and save the file:
ex: Basic cfg/properties/security/edit/add (your account user name) and below in /permissions for sistem/ you select all and apply...now you are able to change and save the file you want.
P.S. Atention this changes was a original post from Cezbor and i have sure witch it works fine under windows xp 32 bites, there isnt any garantee wich it will work under windows professional 7 at 32 bites or 64 bites or other... i will test this on my pc and i will post any results about this experience...thank you!
Good Hunting!
