How do I get Draftsight to work on my imac?

I want to use draftsight on my imac.  I have used it before but now it will not startup.  I think you need to re register every 12 months??

so I have tried downloading the newest version but it will not work.  Here is the message that I get:

"This product is not licensed or has expired"  This was the message I got before we went and downloaded the newest version.

This is the message I get from the newest version:  Which might I add has the logo with a circle and diagonal line through it.

"You cannot use this version of the application DraftSight with this version of Mac OS X"

It is a Mac OS X Version 10.5.8 and it has a Intel Core 2 Duo  which is a 64 bit cpu.

What can I do to make Draftsight work?

I thought about uninstalling Draftsight then trying again, but am worried I might loose the drawings that have already been made???

Also do I just drag the desktop icon to the rubbish bin to uninstall mac apps?
