Looks like novaexchange is in the old chain. The pool probably is blocking the withdraw request to prevent people lost coins if u had an old address. Update your exchange and wallet address at the pool.
Hey, if I had a small amount of coins in my wallet before downloading the new wallet and I update the pool withdrawal address to the same that I had before, will I get my coins? I know that the question is weird, but I have such situation for the first time so I'm making sure that it's gonna be alright.
