It still looks like a water texture problem to me. You could uninstall FSWC and see if that fixes it. If not, then try a "repair". If that does not work, then a reinstall would be about the only option left.
To me, it looks like the Alpha of the water texture is messed up. Check your FSX/texture folder for a file called "water.r8".
Also, since I do not have FSWF, double check to see if there is a specific version of FSWC for the version of FSX you are using (Basic, SP1, SP2, Acceleration). That may make a difference, but I'm shooting in the dark on that.
