maybe it takes a bit longer to confirm the deposit, check again in a few hours after the deposit and it should be there (if nothing went wrong).
i opened a support ticket and then half an hour later the coins were deposited .... now i sent some more coins and again they dont show on the deposit list (they used to show up right away and one can see their 25 confirmations progressing) but now not anymore ... or at least today!!
when i was checking the deposit address, at the bottom of the window where it shows the address it shows also which block they are at ... when i tried earlier today it showed (0) .... now after i got those coins, and before transferring the second batch it showed 103780 ... which was at least 100 blocks behind at that time ... now i opened another support ticket for the new batch and waiting for it!!
they seem to have a problem with their node or something!!!
