How much time does it take to payment process? Some payments freeze at last several days.
50% neoscrypt coins sign:
"We are short of this currency. Please switch to another currency until we find more blocks."
Some coins, mined 5 days ago, still have not arrived.
This has been covered extensively many times in this thread.
If the pool hasn't mined enough to pay in that coin, it does not exchange for that coin; it waits for it to be mined and sells your earnings at current market rate in the system to people requesting BTC as payment. This is why it is suggested to use BTC as payment; as you aren't waiting for enough to get paid. There are many warnings in many places about this.
Also now that I have available a special password switch zap= you can mine the coin directly and help catch up the wallet.
