Although the following should have been fixed by uninstalling and re-downloading, just maybe check the following:
If there are any .OBJECT files in FeralHeart/exports delete them, as they cause this problem.
If there are any weather files in FeralHeart/media/sky or FeralHeart/exports that are not there by default (I.e. downloaded) Then you may want to consider deleting them
Going into FeralHeart/media/particles and checking for doubles, files that end in _0, _1, _2, etc. If so then delete them.
If you exported any maps recently with large object groups then that also may cause a problem.
I hope you get it fixed!
