Try this:
Open My Documents Folder. Go into folder "Mount&Blade Warband". Open "crpg_beta_config.ini". Find the line "bHttpServerQueries=false". Change it to "bHttpServerQueries=true".
Start c-RPG with WSE2. If it finds the servers set them to favorites (so you never have to search servers again). You should then be able to set the line back to "bHttpServerQueries=false".
Worked for me.
