many thanks for the detailed info, Dakota.
EventType: InPageError
A rarer one. It tends to be associated with disk/file damage.
The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
XP instructions in the following document: How to perform disk error checking in Windows XP
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, does iTunes launch properly afterwards?
