Module stopped working

When I first installed the module, I thought it wasn't working, but I just hadn't waited long enough for cron to run. Then it worked properly for about 12 hours or so, then stopped working. When I first installed the module, caching was disabled, but while the module was installed, I had enabled normal caching. I thought maybe this is what had caused the module to stop working, so I disabled caching, but the module still doesn't work. I do have poor man's cron enabled.
