I read related posts about Cu3er branding, and I bought a pro account from them. As you guys suggested I also changed the swf file with the one I got from Cu3er site. However, it didn't work. I contacted Cu3er team, asked for help. Their response:
"We have exported your project, from exported xml added license to xml that you are using for CU3ER on http://www.gourmetmarketing.net.
Just overwrite the xml that is on your server with the one attached as it holds additional license."
My question is about the location of xml file. File name is config.xml and I couldn't find it under Brightbox theme folder. Please advise.
