Sambapos3 error massege

Hi I’m using V3 with SQl and I’m getting this error masseges
the type initializer for ‘Samba.infrastructure.setting.local’ threw an exception.
any one can help .

You need to post in sambapos.org this forum is V4 and V5, sorry most of us havent used V3 and youd probably be best posting in the V3 forum anyway
