This seems to happen for those who do not use razor and instead connect using the shortcut the installer places on the desktop. The problem was that the shortcut linked to the wrong client file. This has been corrected, and a fixed version of the installer has been uploaded which should create the proper shortcuts.
To fix this without having to redownload and reinstall everything, just go to where you installed Sylvan and find the decrypted client file (Decrypted_client.exe) and create a shortcut to it on your desktop. Use that shortcut instead :)
Cypress is The King of fix and keep sylvan fun. Love ya sire. In a manly way of course.
