Nonce error in wallet

[patidarmanoj10]

Returned error: Transaction gas price is too low. There is another transaction with same nonce in the queue. Try increasing the gas price or incrementing the nonce.

I tried higher gas price too but transaction is stucking. I am exporting from ropsten to morden and this error is on ropsten

try sending "0" ETH to your own wallet with a higher nonce, this should cancel the previous transaction and you can try again
