I transferred 75 mBitcoins into my Electrum wallet, but there seems to be a hang-up from my previous transfer of 50mBitcoins which I paid out and purchased with, but still seem to be there.
I spent 50mBitcoins after I transferred the 75 so I should have has 25 left, but my balance is showing 75 and whenever I try to move it out it comes up with an error ("input missing").
I need to talk to somebody from Electrum to find out why my money is locked up in my wallet and I'm unable to transfer ..

Can anybody help?

Thanks.
