So you are stuck with a beta that expires and no way to upgrade to a full version ?
And they can't provide you with an upgrade so that at least that beta doesn't expire ?
There might be a workaround to have the forum display the correct date even when the server doesn't have the correct date.
But it requires some maintenance.
Say the beta expires on 2001-01-01, then you would probably be using a date set somewhere in 1999 to be safe.
If you set the date to the current date -x years, then you could still have the forum display the correct current date and get the cookies to work properly.
You just have to change one line in config.asp. Change:
strForumTimeAdjust = DateAdd("h", strTimeAdjust , Now())
to:
strForumTimeAdjust = DateAdd("yyyy", strTimeAdjust , Now())
Now, instead of adjusting the servertime with hours, you adjust the servertime (and thus date) with years. So if the serverdate is 2 years behind you would set the Time Adjustment: in Server Date/Time Configuration to 2.
I haven't tested this, but I think it should work.
