/*
 SECUROM OEP SCRIPT (not main executable Version 1.1)
 By Nukacola

 This script is using the CreateEventA method to get the OEP of a Securom wrapped file
 it should only work with the other executables. For the main executable use my other script.
 You have to run your securom protected file one time in olly before using this script or it
 won't work correctly. If you have the plugin installed, which deleted the udd files from olly directory you
 have to run it each time before you want to use this script.
 I guess it's working with Securom from ??? up to 4.84.75
