VBS runs... then gets tired?

Howdy,

I have a Macrium Reflect VBS script that generates an image of a small partition every thirty minutes, and sends an email when the script runs. The script launches at system startup. The system running Reflect is a peer-to-peer "Server." That is, it runs XP, but the system is not used as a workstation, it is simply a repository for shared files.

The script works just fine, until it "decides" to stop!

Sometimes, it runs perfectly for more than a week, and then it stops.

When it stops, there is no error, and there is nothing in the Reflect log. The script simply stops running, and I am baffled.

The complete VBS code is just below, and I would certainly appreciate any help in sorting this out,

Lothar
