getting periodic error on asp.net website: An error occurred creating the configuration section handler for fluorinefx/settings

Question

I'm getting the error below periodically on my asp.net web app that is using fluorinefx as a communicator between flex and sql server 2008 database: I'm using Flex 4.6, Fluorinefx runtime version 2.0.50727; .net framework 4.0

Exception information: 
    Exception type: ConfigurationErrorsException 
    Exception message: An error occurred creating the configuration section handler for fluorinefx/settings: Could not find file 'C:\Windows\TEMP\5lggbw23.dll'. (C:\inetpub\wwwroot\Prop84\web.config line 29)

   at System.Web.HttpApplicationFactory.GetSpecialApplicationInstance(IntPtr appContext, HttpContext context)
   at System.Web.Hosting.PipelineRuntime.InitializeApplication(IntPtr appContext)

Any idea of what is causing this error? It cant seem to find the file 'C:\Windows\TEMP\5lggbw23.dll'?

The frustrating thing is that the error seems to come and go
