I've updated the release packages with the fix for the contact form issue, if you download version 2.3.3.2 again the only files you need to replace are the mojoPortal.Features.UI.dll and the mojoPortal.Web.dll in the /bin folder
Regarding item 2, the event page error was perhaps logged by another visitor. The instructions are to visit /Setup/Default.aspx after uploading new version files. It does have error handling designed to assist this by redirecting when it detects certain unhandled errors it checks if it needs and upgrade and tries to redirect to the Setup page if it does. So I do not see any unexpected behavior from what you reported. It logged some errors and also logged that it was redirecting to setup.
Best,
Joe
