Okay so its worked before but now the game won't see the extra vehicles I have put in to game. My friend gave me the files to copy and paste in to my game and when I go to type in the command line in game, it says invalid model. Yes its spelled correctly yes the newveh.img is in PC/models/cdimages and yes the newhandling.dat and newveh.ide is in common/data. I have no idea why the game doesn't see it. Ideas?

Can you provide more information about the mod itself, where you got it from etc. Specs and such information would also help. 

The vehicles are 2 CVPI and police bike. Police police3&4.

Computer is windows 7.

8 gigs ram. ASRock LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard Z77M

HIS H777F1G2M Radeon HD 7770 1GB (128bit) GDDR5 2x Mini-Displayport HDMI DVI (HDCP) PCI Express X16 3.0

Intel Cpu Core 2 Quad Q6600 2.4Ghz Fsb1066Mhz 8M Lga775 Tray

the 4 vehicles we have put in as newveh.img with the files newhandling.dat and newvehicles.ide. Not sure if I missed over something. Our modder and tech specialist left the group and was the on who put it together a year ago. I had reinstall the game last week and I thought just dragging and dropping in would work. But the game doesn't see it and says invalid model when I attempt to spawn it.
