The error in license check means your temporary license has expired. If this is a newly installed trial edition, you might consider just reinstalling and starting over.
Also, if you search on Google with "site:scn.sap.com sap* password" you will get dozens and dozens of hits to threads here where people ask this question all the time.
If you do reset your SAP* password and regain access, you'll find that you can only login to client 000 and only with user SAP* while the license is invalid. You can go to tcode SLICENSE and create a new temporary license.
