I think i found the problem.I sent a payment to a company that uses bitpay and i now realized i had my wallet on the payments settings set to blockchain.info.
Now i set it to bitpay, closed and opened again the wallet, will it be able to send the money? or will i have to do something else?
What is the TXid of the transaction (or the sending address)?
Has the transaction confirmed yet? If so, you'll have to contact bitpay if the funds haven't been added to your account (I assume they get a lot of these problems recently due to the volatility of the tx fee (the recommended amount changes very often).
