Deleting personal data, impossible. Contacting Solidworks, impossible.

I was about to try Solidworks, but unfortunately it did not work at Win10 64bit, even with hotfix.. After free trial installation, I have received mails from Solidworks. Now I have tried to delete my personal data from Solid works, but again no chance, Only error "Email Address is incorrect(SBL-EXL-00151) Error line: 131(SBL-EXL-00151)". But for some reason, I am able to edit my communication preferences with that email.. Is this software really working..? I'm not very convinced. And to get support directly from Solidworks, not possible.

I have to say that I am a bit of pissed off.
