Hi Armin, good that you checked the Lavasoft thing first - we can dissmiss that possibility. Where did you download your trial version from? What Windows version are you running? The answers to these questions might help.

Hello Elisa,

Thanks for your reply.

Being just a computer user, I dont feel comfortable to folow your installation procedure, modifying registy etc.

Could you please repy to my question in the first post please:
