'Under Siege', causes the programme to freeze-up.
Please send me your coollection file so I can see if it has a problem.http://www.coollector.com/help.html#coollection
My email address is hector at coollector dot com
I've tried updating the programme and it gets some way into that and then aborts.
What's the version you're currently using?
Please install the latest version by downloading the installer:http://www.coollector.com
Don't uninstall anything. Just install.
When you'll have the latest version, you'll tell me if you still have problems with the updates.
