Addon cars not working?

[Woah]

Hey all,

I'm sort of new to the whole gta modding thing and the forums, all i know how to do is add cars. Last night I had maybe 15 cars that i added in via DLC. Then out of nowhere they all disappeared, and when I went to spawn them in again it says "Invalid Model" when they were working perfectly fine an hour earlier. I couldn't find help anywhere else so I figured someone on the forums might be able to help me out. I have already tried reinstalling and starting over but still the same thing. I even followed tutorials on youtube in case i was doing something wrong which I don't think that I was. Any sort of help would be appreciated.

Invalid Model could be a lot of things, so try answering these.

 

1. Did you disable your mods, play GTA Online, then forget to re-activate them (OpenIV mods folder for example)?

2. Did you install a new vehicle recently?

3. Are your cars all in one DLC archive or separate ones?

I guess ill hop on since Woah hasn't.. I'm having this exact same issue, and like him; I'm also pretty new to modding. Answer to your questions-

 

1. No, I play offline strictly.

2. Many, yes. Aha.

3. I believe all in one.. But since i'm unsure, is there a way to check??

I've been having the exact same issue as both Woah and teeburt, and I'm pretty new to modding myself. I only ever play offline and have only tried to install 3 or 4 addons and as far as I remember they are all in one archive.
