Hello Tom,
I know you know about this problem and I have worked with WP on my problems with the PLUGIN FAILURE.
To get by, I have been able to delete the failed update and install the new copy as NEW.
However, I cannot do that with a premium plugin unless I have some sort of access to an account I have online with the author. I have 5 sites running with version 1.1 of the gp-premium. Is there a way to get the new version in a file?
Using my original receipt it tells me the download has expired, which I understand. Can you help?
