[SOLVED] proteus 8 professional simulation difficulties!

[meche]

Please can someone please help!

I am new to proteus simulation and currently trying to simulate a simple led ON-OFF project. I wrote my code using MPLAB X IDE and XC8 compiler. But each time I run the simulation I get the error message below:
[ISIS Release 8.02.02 (Build 18911) (C) Labcenter Electronics 1990- 2014.
Compiling design 'C:\Users\meche1\Documents\test.pdsprj'.
Netlist compilation completed OK.
Cannot find model file 'CRYSTAL.MDF'.
Pin '2' is not modelled. [X1]
Pin '1' is not modelled. [X1]
Simulation FAILED due to netlist linker error(s).
]

What am I not doing right?

You need to run Proteus as the administrator for it to find the models, also are you sure the crystal you have chosen has a model?

Thanks for your contribution. I logged on as administrator and my simulation was successful. my LED blinks according to the delay i choose
