Intermittant 'Keyset does not exist' error.

[SteveMM]

Hi having the following problem to do with ChartFX version 6.2.

I have a problem with the following exception being thrown intermittently when a user views a page with a ChartFX chart on it.

The error seems to have a greater chance of occurring if the user has not accessed a chartFx chart for a while (a day say).

The following is a copy of what the error loggs in the windows system event viewer under the application events.

Event code: 3005

As well as this I have found the following on the ChartFX forums which describes the error and some suggestions for resolving it - none of which worked for me.

Things I have tried.

1. Changed the application pool property identity that it was running under from Network Services to Local System, and disabled anoymous access to the chartFx62 directory and the chartFX.config.xml file in the wwwroot directory
