invalid key

I have EasyRotator running on my client’s site and one day it just stopped working for no reason. I managed to get a couple of the old galleries to run, but I can’t get any new ones to run now. I posted what’s happening on the sample page.

These are the errors I’m receiving:
Invalid rotator ID specified (path erc_16_1346977380 doesn’t exist). Unable to display rotator.
Invalid rotator ID specified (path erc_63_1349747358 doesn’t exist). Unable to display rotator.

I contacted my host and they said nothing is wrong on their end.
