Cant access pluggin

Hi there,

Is it possible to edit the price field of the pluggin via the pluggin editor on WordPress? or is there another way?

At the moment the pluggin is working fine but when I try to go in to do some editing it throws up a fatal error page.

I just need to find away to edit the pricing in the pluggin as my pricing has changed.

I don't want to delete the pluggin as I don't have the time to redo things via another pluggin.
