Did you set Windows Explorer to show hidden files and folders?
Search your drive for autosave.dxg (in Windows Explorer, get as far along the c:\users\name\... path as you can, and use the search box in the top right).
You should be able to talk to Wesson again on the enchantment platform, assuming you made a choice at the totem. If you enter the battle tower without making a choice, an enchanter will be chosen randomly, and you'll be able to talk to whichever is left.
On the enchantment platform, you'll also be able to use the enchantment machinery yourself, without having to talk to your enchanter. I did that because it was faster, and I didn't have to hear from Wesson's wife.
There are a couple things you'll need to talk to the enchanter about, though (platform upgrade quests, upgrades for servants).
There is a teleporter shrine you can use to get back outside on Sentinel Island. You'll need to use that to get the quest item what's-his-name wanted from the boat in the tree, though you may want to use it yourself, rather than hand it over to complete the quest.
