I guess the problem is on the senders side, most possible reason is using not enough gas for the token. You should contact the people incharged of the sending of tokens.
This is the nearest possible thing to be done which you should contact the people who are incharged on sending the tokens.They probably didnt have gas to send up the coins successfully. Other possible reasons if you didnt able to recieve airdrops then you might not being considered to be part of it or didnt able to make through to the accepted participants.For now i dont suffer any kind of problems just like yours and im also a airdrop hunter which i do successfully gained or earned free coins without any problems on using myether wallet.
