did this work before with zwei-stein? if so, you might be using damaged 3gp files, so try it with another one. if it doesn't work with any files, but it used to, there's probably a process or program running on your computer that caused a problem during the conversion. use the following instructions to determine if this is the case:

To convert 3gp file, you'd better install a correct decoder, perhaps Haali Media Splitter or QuickTime Alternative.
Btw, I've tried many programs to convert 3gp to other formats, but much perfer winavi.
