could you post a screenshot in form of a picture (f.e. jpg or png) ?
if you uninstall and reinstall qlikview, the documents (.qvw, qvd) are ,of course, not lost.
to activate the license of the client, you only have to connect to the sever after installation.
just connect to the server, open a document, and after a while the client recieves the license, restart client and your done.
