Weecow,
Hello. Not sure why you would need to delete the cascadeinfo.cas file. So far, Cascaldeinfo.cas has nothing to do with your issue. And please do not delete your Pit file. I am guessing you are a standalone installation. We see this error occasionally with a standalone. If you are a network, this is totally different. If you don’t know if you are using a network seat, you need to talk to your IT manager. If you are just a one man shop- likely standalone.
You need to uninstall and reinstall. I have a process for you. First, uninstall the program through the Control Panel.
After this, run the MS Fixit uninstaller and see if the product still lists. If it does, uninstall it.

Next, delete the MAX program folders in these locations (they should be clearly named).
C:\Program Files\Autodesk\
C:\ProgramData\Autodesk\
C:\Program Files (x86)\Autodesk\
C:\Users\All Users\Autodesk\
C:\Users\**YOUR USERID**\AppData\Roaming\Autodesk\
C:\Users\**YOUR USERID**\AppData\Local\Autodesk\
After these are deleted, I would reinstall as an admin with UAC and antivirus turned off.
Thank you for taking part in our community!
