You should try changing your rendering system using this (http://www.feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&topic=43234.msg600118#msg600118) tutorial. When you reinstalled the game, did you make sure that all Feralheart-related files were deleted from their location (likely the C: drive on your computer) before getting a new setup? Of course this excludes any files you purposely saved somewhere else to avoid being deleted, such as presets, etc. You could also check for duplicate particles in Feralheart\media\particles and delete them - They'll look something such as aura_0 or water_1.
