MORE INFO:

Started with SandKlock's "Back to Top" app.  Here is how it went... I purchased the APP from SandBlock through UNA App Market, when I clicked on download it did not work and kept getting hung up when I tried again.  When I presented this issue to SandKlock, he said he could install it to my downloads himself... gave him access to cPanel and he installed to App Market Downloads... I clicked download at that moment and it installed OK... then later went back to purchase different App and I could not get access and received this error message,  (this is for my second site famlli.com)
