failed to restore world state

[Hugo Montes]

Well , what can i say.
First of all thanks for that extense and clear response.
I hadn´t had the chance to get to my computer untill today.
It happened that I opened the program today and it is working fine not only for a new Project but for the same file wich started the problema.
I believe my computer needed some vacations.
I will keep in mind this response in case needed.
Thanks a lot
Regards!!
Hugo
