Basic changes to open source program

The Opensource program is [login to view URL] (As per the stated copyright info, it IS legal to modify this program). I have been using and legally distributing an open source program. I rescently found out that the logo and name with the program was not supposed to be copied. I need for the icon (logo) to be changed for the desktop and within the program, to a different one and anywhere there is referece to the current program title, switched to a differnt name. This is completly legal and you will see once you view program and conditions of the programs open source. Will also need current web info that is on the program deleted. ie: registering info, etc program can be downloaded or I can send a disk. Prefered since it includes the updates). I have already had the Mac version modified a year ago and would like this project to be similar. Can provide Mac version for comparison.
