Flex Viewer 3.6 apps failing to load/display in browser

Hello,

I recently updated to ArcGIS Viewer for Flex version 3.6 from 3.0. My applications were view-able in the browser (chrome) through local host until I updated the builder. The operational layers load in the builder and I can see the application data load from server in the builder preview window.

I have double checked that the inetpub/wwwroot folders have the correct permissions set. All of my URLs are the same, used in the applications built on 3.0. I had no custom widgets installed.

Literally, everything was working in 3.0. I backed up all files and installed 3.6 and now the local URL loads a blank/white page.

Any idea as to what I am missing web server technology wise? I had a web GIS class over two years ago, much has fleeted my brain. Any tips to try to get things back up - are greatly appreciated.

Much of the forum info i have scoured has been no help. Bjorn Svensen can you help?!:D

I am running ArcGIS Viewer for Flex 3.6 with Services from ArcServer 10.1. I have made sure my adobe air and flash files are up to date. (v13.0 of air and flash) I have IIS installed as well, and I am running on a university managed server machine with full permissions.

Thanks - Amber
