I'm getting the same problem... But I heard that if I set it to offline mode I wont gain gold or XP. What should I do?

Then go to where you have crpg installed and delete the file "filelists.txt" (or move it to your destop if you're worried about deleting it)
Then open the crpg launcher and tick the box repair (right hand side)
Then click play crpg
EG. My computer, C:, Program files (x86), Steam, steamapps, common, mountblade warband, modules, cRPG -> locate and delete "filelists.txt"
