If you only recently started using bitcoins, you should know there is a "warm-up period" before you can use your client. It will be downloading information from the network in order to be able to redeem the transaction. You can tell if this warm-up has finished by looking at the part of the client that says "x blocks." As I write this there are 131378 blocks in the network. If your client indicates 131378 or more then this is not the problem you are experiencing. However if the number your client indicates is lower than 131378 please be patient, in a few hours everything will be sorted out.
