I had a whole night of stress trying to figure out why I got the message 'Internal Server Error' but after much prayer and trusting God, I awoke the following morning and did a 'System Restore' to some point before I re-installed Wingate and the client. To my great pleasure, this worked. The settings were reset to a working condition.
I am running Win XP on both the client and the server. I am not sure why the client had stopped loggin on to the net. It worked the first time I installed wingate but after attempting to tweak it to my liking, the client refused to work. The server continued working.
I hope this helps anyone who still has the problem.
