Hi, I followed the tutorials and got it installed, tried to reinstall but I was still getting the error..
first error I got was:
Exception in Script: Plugin(RefCalculationsLib) has not been found
which I copied into my plugins folder to make that go away (not sure if that's what I should have done but it got it to go away..)
then after that I get
[banana]Unknown identifier 'RAbyss_InRandom' at line 24
Compiling failed.
[Error] C:\Simba\Includes\Reflection\./lib/antirandoms/Antirandoms.simba(25:18): Unknown identifier 'RAbyss_InRandom' at line 24
Compiling failed.[/banana]
not sure what to do there since line #24 it brings me to is:

which doesn't have abyss in it at all, not sure
nvm flight helped me
the fix was to change all the stuff in antirandoms.simba on the top to:
{$i ./Abyss.simba}
{$i ./Arnav.simba}
{$i ./BeeKeeper.simba}
{$i ./Certer.simba}
{$i ./DrillDemon.simba}
{$i ./Forester.simba}
{$i ./Frog.simba}
{$i ./Gravedigger.simba}
