Reminders not working sing 3.1.12

Hi,

Invoice reminders have stopped working for me since updating to 3.1.12

The one click update stopped half way through, and I had to do the database migration from the command line.

Everything else seems to be working apart from that, and they used to work before.

Can any one shed some light?

Also can someone tell me the command line to force the reinstallation of a version

Thanks
Jamie
