Hark! Coding!
Has Feral-heart always been crashing for you or did it just start doing so? Have you installed any modifications, maps, presets, etc. recently whose installation processes may have been done incorrectly and are the cause of the issue? If you have tried all of the steps in that thread linked to you above, then I can assume you have already browsed through your particles folder to see if there were any duplicates (files ending in _0, _1, etc.) and removing those. I can also assume you deleted everything and reinstalled the game, arr? If not, you can try that or you can simply restart your computer as well. It also wouldn't hurt to switch rendering systems. If you are playing as OpenGL, then try switching it to Direct3D9 either by going into your Options or going into your ogre.cfg file found in your main Feralheart folder and changing the top portion to the correct rendering system.
For installing the items, have you made sure all the files were placed in the correct folders? Make sure you have placed all of the downloaded files into your Feralheart > Media > Items folder. If you have done that, check the coding in your items.cfg found in the main Feralheart folder. If the items pack came with its own items.cfg, paste that into the Feralheart folder and allow it to replace the current .cfg when requested. Having installed it incorrectly may be the cause of the issue but if not, try some of the other things I suggested in my last post.
Are you using a mac? I know a bit about getting old Feral Heart to work on a mac. If not, i'm not sure I could help.
