Dynamics POS 2009 Add In 'Access denied' issue

Hi,

I'm not sure this is the correct group for posting this issue;

Currently I'm running into an issue with a developed Add In for Dynamics POS 2009.
I'm getting an "Access denied" trying to save the configuration with the following method; Microsoft.Rms.AddinAdapters.Core.AddInConfigurationAdapter.Save(Byte[] configurationBlok).

The configuration is not being saved to the store.

Any idea what's the cause of this issue?

Regards,

Eric
