New folder "PDF Architect" on every document opened

we are using PDF Architect V5 in general all is working just fine but one problem occures regularly. as soon as a pdf file is opended with pdf architect a new folder named "PDF Architect" gets created at the pdf's location. this results in a large number of emty "PDF Architect" folders around the network. I have no idea how to disable this, i m glad for every hint.
