please!!!!!!!! after a week no answer!!!!!!! some one help me

hi friends i add some render elements in render setup .I need them for post production. i added vray lighting ,vray total lighting, vray global illumination ,vray extratext, but in thoes renders i have no light and every where that i had set vray light( sphere or plan) is dark.and in my vray extra text render some of my glass is rendered green. Furthermore in my alpha channel my glass material are colored. i have rendered this file before with a daylight HDRI and every thing was ok. but when i tried to make a night sceen and changed my HDRI to night hdri and set some vray light(sphere and plan) to illuminat my interior spaces, i confront with this problem.you can see my RGB render and alpha channel and vray lighting render element below. i need help.

i advice 1- in iradiancemap setting put subdivis on 100 and interpolat sample on 40. it will cause your render time longer. but usually gives a good result 2-in your render element tab add vray lighting and vray shadows elements.after finishing render progress , in framebuffer window you can see those two element you have added .if there was noise , you should increase your lights subdivise. your hdri subdivs and every light you have use in your sceen.
