I recently upgraded my HD and copied my entire old one to the new one. since then i'm unable to lunch Visual Cobol for Eclipse. Sounds like the license is linked to HD serial number and not MB!!
Called the Canadian Support line couple of weeks ago, and they opened a ticket for me, but unfortunately up till now didn't receive any feedback from them!!!
I still have the old HD and can re-install it if needed to export license.
Thank you in advance for your help
