I bought the script with "professional installation" and for removing the copyright and Yabsoft after 10 days I answer to the request for installation at this point thus: "TO REMOVE THE COPYRIGHT-(" POWERED BY Yabsoft ").
You can edit skin / name / footer.html to remove the copyright information. "After another 10 days to wait for professional installation! It did not installed me the flash upload, and during customizing I remove the copyright as Yabsoft tells me, to get ahead" limited control panel "?? Now I guess I'll have to wait another 15 days for Yabsoft deign to answer me. Thank you for this service Yabsoft so immediate and the script that fails every now.
