Trying to download Cool MP3 Splitter 3.0 for Windows 7, but it will not download. The one I purchased quit working. I want the 3.0 version.
According to the official website of the application, version 3.0 does not exist. The latest released version is 2.02 and can be obtained from the official website of the product.
However, you can check the database of Software Informer for additional products compatible with Windows 7.
Do you mind using another professional MP3 splitter? If not, you might as well have a try with Joyoshare Audio Cutter. It gives the free trial version, applicable to Windows XP and later as well as Mac OS X 10.8 and later. With it, cutting and splitting any audio and video won't damage the original quality.
