Could be a few things, which most likely isn't something you would like to hear and I understand that and want very much to help you solve this quickly....
 
1. Modded vehicle may be bugged in some way, causing a crash. This could be any vehicle you have, so mod them 1 at a time to see which one it could be.
 
2. If you simply "replaced" the files for LCPDFR 1.0d, then you may have a problem. I had this problem aswell, turns out I had to completely delete LCPDFR before installing 1.0d
To do this, run the uninstall.exe, and then after that completes, do a manual cleanup of everything LCPDFR related including the LCPDFR Folder, ScriptHooks, and AdvancedHooks. Delete them all and the logs with them. Then you can simply copy/paste the LCPDFR 1.0d Hotfix folder into your directory.
 
3. If you have a saved vehicle at a safehouse, even if unmodded, it will cause problems. Move that vehicle out of the save location, save your game, enjoy (hopefully).
 
4. I have found that getting the SMPA60 error is in my case always related to a bad mod. This could be a weapons/audio/vehicle/script mod you're using. Install mods 1 at a time. I wait for at least 30 minutes of game time before I say a mod is good and will not crash my game.
 
5. VP Callouts has not yet been updated to be compatible with 1.0d, I suggest uninstalling that mod until an update is released.
 
Here are the mods I use. But remember to do the above mentioned tips prior to just installing what I have.
 
These can all be found here on lcpdfr
LCPDFR 1.0d Hotfix (of course)
ENB SFE (graphics mod)
ELS V8
GTA IV Cop Manager (manages the amount of police officers and their cars in the game, helping to prevent crashes)

EDIT: I never crash with my current setup... Ever.
 
I really hope this helps you in some way or at least guides you in the right direction.... Happy gaming :)
