Upgrade CRASH! Help!

I am in the process of upgrading our internal instance of Sage CRM from v7.2 to v7.3. Please no comments on how long we waited to do this for ourselves :). I just received an error I've never seen nor can I find any related info here on it. The error reads:

An error occurred during the move data process: -2147024784

Component: CRM online help files
File Group: onlinehelp
File:
C:\CRM\<installname>\WWWRoot|Help\FR\Administration\Content\Resources\Images\SysAdmin\Hosted39.rra

Any ideas or guidance on what could cause this error would be appreciated.
