Thanks for chipping in. I've seen those threads, but there is scant help to be found on this issue.
I have contacted the author, but still await a response. This is strange since many people seem to have the same issue and it has been going on for some time. Maybe he/she has other issues that prevent them attending to this.
It's a pity though , since Vaicom was such a good idea and a lot of work has obviously gone into it. But for the present it appears to be fubar.
