I'd highly recommend Minera for your gridseeds.
Also, keep in mind the difficulty has skyrocketed since 2014, so you should set it appropriately on the pool side.
I would suspect this is the problem as well. Your little gridseeds are so old that even finding a default pool share might take quite a bit of time. As wavelengths said, if it is possible to adjust your difficulty on the pool you are using I would start with that.
