By now I wonder whether you have managed to successfully download the music that you've purchased. If so, this may be because the cause of the issue has been corrected, either by a re-start of your computer or because an online problem has been sorted out.
If you haven't yet tried again, I suggest that you do so now.

Plus, I think I was over charged ...my store credits went from $75 to $39.89 just for two albums!
My understanding of the US retail system (assuming that is where you are located) is that the price does not include sales tax, which is added to the total cost of the two albums. So without more detail of the price of the albums and the local sales tax in your state, there is no way for anyone here to comment on that (other than my observation).
If you think that your claim is valid, you're more likely to get back any overpayment by taking the issue up with store.
