I have a resolume arena server running v-control to do some projektor and air conditioning powering on and off. The arena server was triggered through the localhost network adapter (127.0.0.1 in v-control). After a recent update to arena 7, the network interface in arena changed from localhost to the internal realtek card. That was causing v-control to crash in show load. After i changed the network interface in arena back to localhost everything worked as it should.
thanks for letting us know. Good that you found a work around. Anyhow, this should not happen in V-Control. The result should be that you simply can not talk to the arena server. So could ypo please post your project. Maybe I can find the bug that causes this behavior then.
