get rid of a batch please

A check was printed but wrongly entered as an EFT - using the blue arrow next to the Check box to enter the check.

Now we can't post the batch (batch of 1), or get rid of it because it says a check has  been entered.

We can't edit it, or void it.

GP keeps telling us that it wont be posted. 

"Batch information is invalid.  This transaction contains errors.  It won't be posted."

It also says to use batch recovery, which is a never ending circle. 

Any ideas?
