No problem.
The instructions are a bit cryptic at Autodesk's site on how to correctly install the SP1 updater.

First, you must UNinstall Maya 8.5, then install the 8.5 SP1 updater.
IMPORTANT: You must NOT uninstall your docs!
They are not updated with the SP1 updater, so if you DO you may need to reinstall the documentation from your original CD, as I had to, hehe.
Then you will have the latest 8.5 SP1 Maya unlimited version.
The installer knows which version to install for you based on your license on your machine. (Complete or Unlimited)
Then let us know if this worked for you.
....and for crying out loud, get more ram!
