Umbraco v5 RTM causes iis express to crash - suspected security/config setting

Question

So I'm convinced that the problem is permissions related, but I can't put my finger on it. When running v5 RTM via iis express / webmatrix the site spins up just fine, but then crashes within 7-8 secs with the error message "unhandled excpetion in iisexpress.exe". I've tried setting trust to medium in web.config, which causes a YSOD with excpetion

"System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

I'm working on a machine connected to a Windows domain and have temporarily given "Everyone" full control over the folder containing the v5 site.

Am I missing a specific setting for a service account attached to IIS Express (I thought IIS Express ran as a user process and I am a local admin on the machine)? I'm on an XP machine and don't have the option of installing full blown IIS 7. I currently run other MVC3 projects from within VS 2010 without issue. Also, Umbraco 4.7.x runs within my iisexpress without issue. At this point I'm just grasping for straws in the hopes of problem remediation. I REALLY want to leverage v5 as part of a metadata management project I'm starting, but obviously will be stuck with v4 if configuration will be an issue for myself or members of my team.

Thanks for any suggestions!

Here's the log file contents:

Hmm that's very strange (the first part), do you ever get any pages returned at all within those 7-8 seconds or does it look like it's crashing basically on app startup?

We don't support medium trust yet so the second part / error message you're getting is normal in that sense. But the first one is odd. There's a file at /App_Data/Logs/UmbracoTraceLog.txt that it tries to write to, could you check a) it's writing to there properly and isn't the source of the crash and b) if you have anything in there worth posting?
