Hi. I'm new here. I've been running Maya 7.0 Unlimited on my mac for about a year and a half. Everything was fine until last night. I tried to open maya, the start up box appeared saying it's loading, then the script editor opens and at the bottom of the list are the following two errors:

"// Error: file: /Applications/Alias/maya7.0/Maya.app/Contents/scripts/cloth/buildClothMenuBar.mel line 92: Object not found: //
updateRendererUI;
updateRendererUI;
// Error: file: /Applications/Alias/maya7.0/Maya.app/Contents/scripts/others/mentalrayUI.mel line 1354: Object not found: mainRenderMenu //"

I have no interface. All I see is my desktop and the only items in the menu bar at the top of my screen say "Maya", "Cloth", "Constraints", and "Simulation". If I try to select anything it crashes completely. There's no scene, no cameras, no interface, nothing. I tried uninstalling and reinstalling, deleting the userPrefs.mel, nothing helps. Can anybody clue me in on what's happening? If anyone can offer any suggestions to get my maya working again I'd really appreciate it.

my system specs:
PowerPC G5 dual 2.0 GHz
1 GB DDR ram
ATI Radeon 9600
OSX 10.4.9

Thanks in advance,

Enid.
