Enigma Protector

1. I have a .net application. At first i have obfuscated my application with SmartAssembly software and then i have applied protection with enigma protector 5.30. protected application is running fine(applied only licensing feature).
But when i am trying to applying extra protection on top of protected file, i am getting an error(Application can not be started).
I have tried by uncheck
-Hook entire process to check for enigma api calls

2. Should i select .NET smart assembly hooking option, when the .NET application is obfuscated and compressed ?

Hmm, i think that you should not use assembly compression in SA. It is completely useless and only spends CPU. SA itself is very weak protector. As for the rest, I can not answer, we will wait for a response from developer
