Well, recently i uninstalled LCPDFR, and installed some other realism/Roleplaying scripts, but only one are loading.

I use the First Person script, the Less Overtaking and the brakelight script. Help? I have a ASI loader and the scripthook.

Have you read the script readmes? Because in all other cases you have made a topic, you have failed to follow instructions. Make sure the scripts who are supposed to be in the scripts folder, are in the scripts folder and those who are supposed to be in the root directory are in the root directory. 

For once i actually (!) Read the readmes, but i still don't work. They worked perfectly before, but i guess i can live without two scripts. 

I find that very hard to believe. Some scripts go into the scripts folder and some into the root directory.

I know that. I read trough the readmes carefully, but nothing. Should i considering trying xliveless instead of dsound?

You can try, but there's really no difference other than Dsound being more stable at times.
