Announcement - 20th March 2007

Proton Plus Version 2.1.5.3 is now over two years old and has been vastly superceded by Proton Development Suite. One major feature is that PDS uses a USB dongle for licensing, meaning no more registration codes when you re-install (hurrah!)

If you'd like to upgrade, please read more about Proton Development Suite and follow the upgrade procedure.

Thank you!
