Welcome to AAC!
A thread belongs to the OP (original poster). Trying to take over someone elses thread is called hijacking, which is not allowed at All About Circuits. I have therefore given you a thread of your very own.

I can help you,if you finish work.
You have all your files packaged in zip archive(models, symbols and the electronic circuit).I have an extensive library of models and symbol,but your not. The idea is that on your electronic circuit an element is placed by LT.This element never joins except GND.

Your .asc file is not useful without either all the necessary models or some text annotation to indicate which active components are used.
