Sorry for the questions, but I ask step by step.
1. So you uploaded the zip file of WB 2.13 and the unzip.php via ftp?
2. You have unzipped the zip file of WB 2.13 with the call in the browser?
3. You have logged in as superadmin with the call in the brwoser?
4. Then a link to the update-script should have appeared.
Was that the case?
Because only this administrator is authorized to start the upgrade-script.
Did the updrade-script run through without any red text output?
