You will need Pronto Edit to open the ccf files. You can get it from the Files section of Remote Central.
After you install Pronto Edit, download the ccf file you want and open it. Find a button whose code you need. Double click on it to bring up the Properties dialog. If you aren't already in the Action tab, click on it. Double click on the text in the right hand text box and that will bring up another dialog that has the IR codes in it. Copy that content and then paste it into the IR Code text box for the button back in ORDesktop.
Once you get Pronto Edit installed, it is very quick to copy the codes over.
Let me know if you need any more help.
