Hello all!

Got a pretty noob and URGENT question with the payment id. I have sent a monero(exchange wallet) to my other monero wallet. And the exchange wallet requires a payment ID so i simply generated a random one from the mymonero.com web GUI. Now my Monero coins have yet to arrive for over an hour now.

Question is, is it ok to generate a random Monero payment ID when sending to another wallet? As I have read and understood this is a an ID simply to track the transfer of the coins. And the coins will still transfer with our without the ID or whatever string you input on the payment ID to the proper address.

Also how do you track Monero blocks? Because all I have from my exchange is the payment ID and no transaction blocks? And to be honest I am very worried about losing my coins!

Thanks for the enlightenment.
