"Autodesk" Softimage being a prick. (Will not animate)

Ever since I upgraded to Autodesk’s Mod Tool , it’s been a prick.
For starters , It likes to crash on me when I try and do stuff with the render passes. (This isn’t the main problem.

Secondly , It’s starting to not animate. Sure , It will change the first key , but won’t let me place another.
I’ve done nothing different , It’s all default stuff… I do not understand why it is doing this.
Help , please.
