Ring tones don't work. A message saying files are currupted. Not even the vibrate will work.

simply go into settings messages and turn off message tone

Some how your phone was reset or had the tone turned off. Just follow the below guide and your audio should come back on. I would do a soft reset (turn off the handset, remove the battery then reinsert) before performing the instructions.

Tone settings
To select a ringing tone for voice calls, select Tones >
Ringing tone.
To select a ringing tone for video calls, select Tones > Video
call tone.
To set the ringing type, select Tones > Ringing type. You
can also set the device to sound a ringing tone that is a
combination of the spoken name of the caller and the
selected ringing tone, when someone from your contacts list
calls you. Select Tones > Say caller's name.
To set the volume level of the ringing tone, select Tones >
Ringing volume.
To set the various alert tones, select Tones > Message alert

alarm tone.
To set the device to vibrate when you receive a call, select
Tones > Vibrating alert.
To set the volume level of the device keypad tones, select

You can adjust and customize the ringing tones, alert tones, and other device tones for different events, environments, or caller
groups.
To customize a profile, scroll to the desired profile in the list, and select Options > Personalise.
Define the following settings:
• Ringing tone — Select a ringing tone from the list, or select Tone downloads to open a bookmark folder containing a list of
bookmarks for downloading tones using the browser. To listen to the selected tone, select Play. If you have two alternate
phone lines in use, you can specify a ringing tone for each line.

A possible resolution is to update your device to Windows Mobile OS. For some reason, that seemed to work for customers that have experienced the same problem.
