ESET Mobile Security for Android Issues

I installed the RC version of ESET Mobile Security for Android from the android market place.

Recently, I got a message saying that an upgrade was available, which I dually installed.

This appeared to be the release version and I was invited to apply for a trial to activate the product, which I did, and received a confirmation email of same.

However, the product failed to activate and was constantly crashing and displaying a force close message.

So I uninstalled it. Now the app is not longer available in the android market.

What is up with all of that?

One more related question, I have 3 Eset Smart Security Licenses. If the mobile version is stable and available, I would probably like to buy 3 licenses of that. Is there a discount I can avail of?

Also, I notice the Android 4.0 (Ice Cream Sandwich) is not listed as a supported Android version - will this be changing soon?

Thanks!
