Can you please give some extra info?
There is no ad code at all in the members site area. The new login only accesses members pages - Maybe your browser is caching the page you previously visited?
If you go to
www.simviation.com - force refresh the page (Ctrl F5) & click the Express Members link - enter details.
Any ad code is there from cache as there is zero ad code in any member pages.
Thanks for the feedback - it's always the case that in any upgrade/change there will be a few problems. We take great care in being genuinely on our users side. One report means others are experiencing this too.
We at Simviation never ignore user problems & fix things ASAP - always.

Simplicity is the ultimate sophistication. – Leonardo da Vinci
