I have done the procedure a few times to get the blu-ray to activate. It is something in Corel/Roxio's programing probably because it is consistent and hope they take note of this discussion. Here is what works every time so far...
1. When you click to activate the blu-ray under the Home menu under the Help option in the Finder, immediately turn off your wi-fi or network connection before Toast 19 Pro crashes.
2. This will immediately pop up a notice that you are not connected to the internet and the program needs to be connected in order to activate. It will ask then,"Do you want to try again?".
3. Then turn on again your wi-fi or network connection and when it is active again, THEN select "Yes" on the message to try activating again.
4. THEN the Blu-ray activates and says. "ok".
So...it seems that Corel/Roxio needs to fix this and it might be in the command line to activate if they are programing (I did a little programing before and it looks like the symptoms).
Maybe an easy fix to just direct the command to the correct code for activation.
But...now days...probably Corel/Roxio outsourced their coding, so try to get whomever to fix it might be their challenge without having to pay more...just my thoughts and do not know.
It should be an easy fix now that the issue has been seen to be constant, so it should be easy now to trouble shoot where the error is on the code and correct it...
