NOPing 573782 definately works as long as you also NOP 57389B. Doing one or the other but not both does not work properly, but NOPing both seems to work great.

I know I have thanked you already for your help, but thank you again . It made me very happy to finally get this working, after so much frustration at being unsuccessful. I spent a pathetically long time trying to get it to work, when I knew it had to be a simple solution, and in the end it was. But, I learned a lot (about SEH especially) from working on it. From what I learned from this, I was able to get Recordius 1.04 unpacked and working without even thinking about it, so it was worth it. Maybe one day I can return you the favor.
