Abnormal colors in lightning FS2004

[marcosdegodoy]

Hello, I need some help, I installed some "improvement" of the FS2004 scenery and lightning are now exploding in various colors (green, blue, red, yellow) and no more white. And also the thrust of a military aircraft (F14D) is no longer yellow, now appears green.
I do not know how to revert it back to the default FS2004. Please if anyone knows how to do this please help me!
Thank you in advance for any instruction.

silly question but have you removed your 'improvements' ?

It is no good saying you've added some improvement

You need to tell us exactly what you added.

Seems there has been some base file overights, but pointless to even guess without the proper information from you.
