Newest update wont load my SL anymore. Ive tried re-installing, changing location, and all that.

Ive logged in , it shows the dark grey loading page gets to the end of the bar and just shuts down like its been logged out. It does this every single time.

It's impossible to guess why login is failing for you, since we know nothing about your computer or your Internet connection.  If you want to provide extra information or need to clarify your question, click on the Options link in the upper right corner of your question and select EDIT. Please do not start a new thread. Doing that makes it hard for us to see what other people have already suggested, and it pushes other residents' questions off the page.

When you tried re-installing, did you do a CLEAN reinstall?  See here for instructions on how to do that...and be sure to download the viewer again and work from a fresh download.  The previous one might have been corrupted.
