Are you sure that your rig(s) are set up correctly pointg at the folding pool. Otherwise if the pool shows 18 coins so far then it is probably catching up from the beginning. At are current PPD you should be getting ~20-25 coins per day. However, you still have made ~$30 so far. I would wait a little longer and I agree there needs to be more information about payouts we are working on getting it updated.
I'm pretty certain it's setup correctly. If the payouts are still behind in my case where I've been folding to the CureCoin team since a few hours after launch, then theres more than a 24 hour lag.
Please restart your CPU slot, set it to finish so it not get a new WU if you don't want. But please doing harm the science in not finishing WU. It will also harm you passkey, keep in mind the required 80% success rate.
To make it more secure you can configure the CPU slot with an advanced option "pause-on-start" set true. Will not start the slot after reboot.
But please: finish work started.
