I'm having the same issue. I remove everything and install it, works perfectly for a couple of tries. As soon as I change any file, it stops working and will terminate LSPDFR even though I can still play GTA and menyoo without it. The only files I would add are either a new visualsettings.dat or a vehicle mod. Theoretically, this shouldn't make a difference since if it did, simple removal of the file would not cause the same issue. There needs to be an update in order to patch these issues. I have noticed that it could be the save games that were causing the problems because once I removed the other ones, it managed to work, however this wasn't a reliable solution
