HOW TO PLAY 2007 CLIENT????!!!!

you just play it

SXSTRACE.EXE ERROR.

did you you try uninstaling and reinstaling

I made the post so the developer can fix the bugs

you miss one

the 2007 animation. when you jump.

did you check online for a fix

idk 

why do i  not play 2007 client

say another error for BITL. 

bitl is not notice to errors of 2007 clients of the jumps error animations these error needs to be removed whit then he didnt do that 
did you know clone_trapperNoob1019 made 2007 client for broken at shit dog 

so that clan_troperNoob1019 make a stupid 2007 client

why novetus didnt notice whit another fucking client to replace the fucking content of these client of 2007 client he will see it broken super broken 

And yes i check it but it wont function

 like  disaster hotel, farm tycoon work at a pizza place I used the clients that when these maps were released

in disaster hotel you can't jump

I was using clients 2008-latest

DUDE if a map created 2011 play it in 2011 if a game born in 2007 you can play it type 2008 2009 2010 2011 understannd!
