Another Pay Pal Problem

I have the free version of aMember. I am trying to configure the paypal. I get the error

"Error Detected
We cannot process this transaction because there is a problem with the PayPal email address supplied by the seller. Please contact the seller to resolve the problem.

If this payment is for an eBay auction, you can contact the seller via the "Ask Seller a Question" link on the listing page. When you have the correct email address, payment can be made at www.paypal.com."

I read on some of the other posts that with the free version I had to find this area in the config-plugins area
############## payment/paypal #################
$pc = array();
$pc['business'] = 'Accout@email.com';
$plugin_config['payment']['paypal'] = $pc;

I found this area and typed in the correct (verified) email address.. Still not working... Is there anything else that I could do to resolve this issue...

Hello Alex,
I have verified that I do in fact have correct info... This is the only editing that I done.

############## payment/paypal #################
$pc = array();
$pc['business'] = 'account@email.com';
$plugin_config['payment']['paypal'] = $pc;

Thanks, Dan
