you will not be able to restore as xvm has been re written in the last month or so , you must have been using a much older version pre july? 

if you wrote your own xvm , you are going to need to recode it by hand as quite a few commands/macros have changed , the shadow command now uses blur for example , this would be the black border you mentioned ,

you can alter default wn8 in your personal space on the xvm websaite , set to two digit xwn8 etc..

recoding this yourself will take you a while , else download someones config that has already been updated and is close to what you had before

markersalivenormal.xc

this needs to be there somewhere, note the speed is the speed the damage floats upwards

reason for three enteries is because one is for your team mates doing damage,one is for your squad mates and one for you, you need to repeat these for enemy damage as well,

note these are for only doing damage not kills , kill text is markersalivedead.xc
