Don't just say it doesn't work but describe in detail what is happening and add the following information:
* VirtueMart version
* CSVI version (Latest is not a version number)
* Sample of the file being imported
* Collected debug information
Without this information you won't get a useful answer. If no debug log is attached, you will get a request to post it.
My customer wanted a VirtueMart order export for Excel and after trying some other extensions, this one was the only one that did the job. I had to filter out some unnecessary Text in the fields, so I used the replacement function. Earlier I used the Free version for simple product import/export, that was fine. The Pro version really has so many functions, you can adjust everything according to your needs. Really excellent work.
