6 day objective isn't enble

when the game start, people can select one of five objective to achieve more experience and up to higher level, however, my issue is since i change the folder of BFI in document ,c:\ . then copy back to the same location, from c: to D: , those objective can't be selected and finished it to earn point, it have over 2 week for the issue, as i expected it will be cured after refreshing week. of course, it didn't work, and i didn't want to reinstall the game to cure, it may or may not work, truly, i doesn't want to reinstall such giant game, over 50G to see the result, so what will be the solution for the issue
