I upgraded last evening from the release version to the current beta.  I found that all my switches and other network devices were gone.  I also had a large number of thin clients missing.  When I scan I see the devices show up and then after a brief period they disappear.  If I do a search by ip or name they do not show either.  They are also not reflected in the client under devices.  I don't think it is an SNMP issue because all the printer are showing.
I am new to Lansweeper and can't find anywhere there may be a setting for this.  I've added the OID for the models of thin clients thinking this would fix it and they still disappear.
This is a new installation and not concerned if I lose data as long as I will be able to get it back once the beta goes into RC.
Thanks
