Welcome to GTA5-Mods.com

I had around 60 add-on cars with this and it worked fine but I added like 8 more and it stopped working, no blip, nothing. Is there a limit as to how much cars can be added? This is what happened in my PDM log:
27/12/2015 12:43:08:Conversion from string "" to type 'Decimal' is not valid. at Microsoft.VisualBasic.CompilerServices.Conversions.ToDecimal(String Value, NumberFormatInfo NumberFormat)
at PremiumDeluxeMotorsportCarDealership3.PremiumDeluxeMotorsport.ReadVehicles(String File, UIMenu MenuCategory, String Subtitle, UIMenuItem MenuItem)
at PremiumDeluxeMotorsportCarDealership3.PremiumDeluxeMotorsport..ctor()
and then it repeats this for a very long time:
27/12/2015 12:43:15:Object reference not set to an instance of an object. at PremiumDeluxeMotorsportCarDealership3.PremiumDeluxeMotorsport.OnTick(Object o, EventArgs e)

Looking through the code it says that when you have a vehicle and you get out the screen should fade. I set the parameters down (to CAM.DO_SCREEN_FADE_OUT(2000) for most/all traders, but when I get a car they want, and I get out, the screen never fades, and I don't get any sort of payment/new blip on the map. Is there a way to fix this?
Also, I can never get to the Ride or Die club without it saying that the car isn't in good condition, despite being no visual damage. Is there a way to fix this also?
Other than that though, this is a great mod!
