Payment errors

Hi That did not seem to make any difference, how do I remove the old version?

You can just upload zip and extract that will over write or you can manually delete and upload updated files.

I will try again to reinstall your update, but if it does not work I'll want a full refund.

Sure your funds fully safe with Litecart. I hope plugin will work at your site. The plugin is already in use on other sites of buyer and working fine without any errors and complaints.
