Search resultes URL not workling

First of all: Thank you very much that you continue the DLM. For me it works fine.

The only thing that I found out is, that the URL of search results is not rewritten be this PlugIn.

For example I have a Download-URL like this:

https://www.harnmaster.de/downloads/download-info/tabellensammlung-hm3-deutsch/

When this Download is lstet in search results (it is actually found without problem), the URL is https://www.harnmaster.de/?dlm_download=tabellensammlung-hm3-deutsch

But this URL results in a 404 Page error. :'(

This is the search result: https://www.harnmaster.de/?s=Tabellensammlung+HM3+%28deutsch%29

Any idea about this?
