ECN is unlikely to be enabled unless you explicitly did so at some point.
The copying program may or may not be the problem. It could be a problem if any of its drivers are permanently resident, to allow packet writing to CDs (where you can write to them several times before finalizing them). For example, EZCD or whatever it's called now.
Basically, SecuRom is designed to stop a protected program running if it thinks you aren't running it from the original media, so it blocks things like virtual drives that could host an ISO image. It also blocks anything that looks as though it could be looking at the data stream within the application, because that could be an indication of someone hoping to circumvent the protection. There are a bazillion ways SecuROM can interfere with your day. Their web site is quite helpful, and will show you how to create a log file you can then submit to them. They'll tell you what the problem is. You can start the help process at

Rant: You'll note SecuROM is a Sony product, and it's the main reason (together with what's known in Japan as the "Sony Timer", where Sony gear is reputed to fail one day out of warranty) I no longer buy Sony.
