Yikes. I feel so bad for you! That is what was happening with ours and we stopped and the next day at about 11:30 began again when it was HOT and sunny - man, that liner stretched like ever. All is not lost, it will go and it will be good. Just waiting on the sun - I see in the forecast that it IS on its way - this afternoon or tomorrow it should be perfect for that liner. Fingers crossed for you.
