Looks like it... I would delete both from disk, redownload 10, and reinstall it. Also check that you didn't run out of disk space.
If all else fails, phone our technical support at 1-800-WOLFRAM, they're pretty good.

Completely removing my previous copy of Mathematica and nuking my ~/Library/Mathematica directory made the documentation formatting errors go away. I'm not sure if that was the cause or not.
However, I still get ExportString messages out of many functions.
General::unavail: ExportString is not available in this version of the Wolfram Language.
EDIT: I'm trying to hunt down why I get the unveil error message. Might this be a limitation of a trial mathematica license?
