Could be a lot of things then, i thought it was only at Fort Dawnguard. But save games not loading are normal if you have tons of mods, you could try starting a new game (if your save in riften is an autosave don't do this! or else you will lose it) wait a bit and then try to load that save in riften.

Also, by restarting your pc are you able to load both saves?
