I sent some coins to Cryptopia from my 1.8 wallet before I knew that their wallet was in maintenance updating to 1.9. What is going to happen to those coins?? Will they show up when they get their wallet updated or are they going to be lost because they will be on 1.9 and I sent them from 1.8??
Not being able to send from 1.8 to 1.9 and vice versa usually means that the TX is incompatible and if it was sent after the official chain forked it won't be included into the 1.9 version of the blockchain. So check how many coins you should have including those sent ones and once your wallet is up to date, synced and still missing those coins look for that TX in your transaction list. It should be sitting there with 0 confirmations, if that's the case go to the console and do a repairwallet which should give you your coins back. If it actually managed to get confirmed, like if sent before the fork happened, check Cryptopia, the coins should be there once they are synced up.
