It's possible indeed.
I'd all but given up with subsims after SH5, but recently started yearning for the open seas and stuff to blow up.
So I purchased SH4 and was quite impressed, got have way through the downloads and received the "you must be new here" message.
Ahh well I'm sure I'll find a way to finish off the downloads
Thanks for replying Jim and nice to talk to you again. I'll try to pop back from time to time and say hi
