Hi, I just purchased and downloaded 1.5.2a, but I'm trying to get the game to start in v 1.4.2 - 3d purposes. Is there a setting to revert back or is there a different download I can receive 1.4.2?

Thanks,

Thank you stepsbarto - ha!, works perfectly. Back to 1.4.2. to play another DHR fix :-) Learn something new every day!
Take care and appreciate the fast response.

Hi,

I also need to downgrade to 1.6.

I don't see this as an option, only to 1.8.

How can I do this?

Support might be able to help you with that by giving you access to the corresponding offline backup installer, if they still have it.

I doubt that this kind of request would be handled with high priority though.
Prepare for a loooooooooooong queque.
