Try deleting your cache in C:UsersAdministratorDownloadsWorld of Warcraft 3.3.5aWTFAccount<your warmane account name> delete "cache.md5" then go into Icecrown or any other realm that is in that folder find a folder with your in-game character name on it and in there also delete "cache.md5".
Also go to "SavedVariables" folder and look if there is more than one "Recount.lua" file if yes then delete them and leave one
Another solution that helped is that i had 2 different DPS/Damage meters one was Skada and other one was Recount so try deleting the other DPS/Damage meters that are not Recount
And i recommend try downloading Skada Damage Meter in my opinion it way better
PS: If you decide to download Skada make sure u deleted the Recount Damage Meter from your Addons folder and while you're in the character selection windows look for for the "Addons" button at the bottom left corner and make sure u check "“Load Out of Date AddOns” and then just press "Okay"
Also what helped me i had 2 damage/DPS counters in my addon folder so i deleted one
