On the Cyseal map if you zoom out all the way, do you not see the waypoint markers on the starting beach (one south of the 2 drunk soldiers, the other on the cliff above where you found the body), just left of the harbour warehouse, etc?
If you zoom in a bit 'The Legent of the Lighthouse' secrets marker should be just below the 'Lighthouse' location marker, and the 'Forgoten Ledgends' secret marker just above 'Undertaker's Hut' location marker (inside, on the straight wall).
Gerome's treasure map secret markers should be a little down and right of the Desolate Farms waypoint, at the talking statues (opposite side as the waypoint), left of the front door to the Abandoned Church (past the trees and rocks), above the church (beside the tree in the corner, up the stairs to the path leading to the fire area) and almost directly above the north gate teleporter (and slightly right) if you keep going up to the roughly horizontal cliff separating that area from the region you need to go through the cave with Arhu's failed experiment to reach.
There is a support form on the Larian support page, which sends an email to supportdos@larian.com, in the case of D:OS and the EE. There isn't a big difference between that and the forum, though, if you don't need to provide saves, etc, since support email comes to me.
