I bought the version in July (8.0....) and yesterday I upgraded (9.0....) the program, but during the instalation a blank screem apear at the configuration screem.
I must close this srceem from the red cross, because no other opcion.
Since that I can't use any program in my computer.
All the programs were blocked.
I had to uninstall ZAExtSec to run excel for example, now I can use all the programs.

Wath must I do to solve the problem.
How can I download the version 8.0

Processor I7, 32 bits
Widows vista
