I'm glad the issue was solved, but a variation of this problem remains for me. My host is a Mac Pro running Snow Leopard and Logic. The slave machine is a new Mac Mini Server running Lion. All versions of VEPro are the same. When I load VEPro into Logic, it won't display any instances from the Mini Server. If I manually establish a connection, it works fine, but obviously is a pain and extra work, especially when starting new projects. Both machines are on static IP addresses, etc. I've tried 64 and 32 bit variations: neither will display instances. If I run VEPro Server within the host Mac, the plug-in will see those "internal" instances.
Any suggestions? Thanks.
