My created WMA file is invalid, why?
If you create invalid wma files, please download wmfdist.exe and install it on your computer, then reinstall our software.

While attempting to edit a WMA file, the software does not seem to respond. What could be the problem?
Unfortunately, a major inconvenience with the WMA file at present is that many files are protected, or locked. As far as we know, protected WMA files cannot be converted with any software. Some WMA files are intentionally protected, while others are automatically protected upon creation by the producing software.

When I create MP3/OGG file, an error " Don't support this MP3/OGG format, please reset. " appear, why?
It is because you have set high frequency and low bitrate or have set low frequency and high bitrate. For example, you have set to frequency 48KHz, bitrate 32Kbps. If so, please low the frequency or high the bitrate.

I want to create small file, how should I do?
To create small file, please low the parameters. But the low the parameters such as frequency and bitrate, the low the quality of your created file, though the small the file. In other words, the high the parameters, the high the quality of your created file, but the large the file.

I want to marge just a part of every file not whole file in to one large file, could MP3 Cutter Joiner do that?
Yes, MP3 Cutter Joiner can do that in just one commmand. Just add the files you want to marge and set start-time/end-time for every file, then click "Join" button, all the parts not whole file you have chose will be marged to one large file. More info...

Please make sure you are using the correct register info. Our register info will be sent as 'Register Name: *** Register Code:*** '.
