First of all, you should make sure you're running stable version of Uplay.
These are instructions how you can fix recent Uplay mess from Ubi representative:

Then turn cloud synchronization off (uncheck the box near the option "Enable Cloud Save Synchronization.." in Uplay general settings) and restart Uplay client.
If it worked, good, if not, maybe some of your saves got corrupted by the cloud. In this case try to do the following:
1. Keep cloud synchronization turned off.
2. Locate your FC4 saves folder ("420" or "856" or something else, read the instructions
here) and back it up in a different place.
3. Open this folder - you will see a set of numbered pairs of
*.save and
*.save.upload files (sometimes it's just
*.save files). Pick only one of the
*.save files and delete all the rest. Now, if the number in the file's name is different from "
1", rename it to "
1". Sometimes there is a
*.save.temp file, you can use it, just rename it to
1.save.
4. Load the game, and see if it's fixed. If it didn't work, exit the game, restore the content of FC4 saves folder from the backup you made in step 2, and try to use different save file as described in step 3.
In the future I recommend to turn cloud synchronization off permanently and instead regularly backup your saves as described in my guide.
If you do so you can always roll back to one of your older saves that wasn't corrupt without losing the entire progress...
There is also a possibility to recover some of your older saves through general system restore to a previous restore point.
If every attempt to restore any of your own working saves failed, you can also take one of my saves (I have more than 100 saves along the game). The last one is at 87%, 3 campaign missions left, 1 outpost and 1 fortress left to liberate, 2 Shangri-La missions and Yak farm.
