How do I fix Time Machine error code 43?

When I try to open Time Machine in my applications folder, it won't open and i get a message with Error Code 43.

I've never set up Time Machine before on my G5. I did add a new internal hard drive about 6 months ago but other than that, there are no other drives connected to it.

I recently bought a MBP and a time capsule. i would like to back up my G5 to the Time Capsule before I start moving data/info from my G5 to my MBP. I've already set up the Time Capsule to work with my MBP. Now I just need to set up my G5.

I've read in another forum that I may need to re-set my preferences in Time Machine (on the G5) to get it to work again. They recommended "right clicking" or "control" click to open time machine. When I do that, I don't get a menu item for preferences. So I don't know how to find the preferences.

Maybe there is something else I need to do or know, that is why I'm looking for help.

Thanks,

Ehren
