I need help!

I don't know what's wrong with my sa-mp and GTA San Andreas they don't work :/
The only thing I did was trying to mod Rasta's character and first I changed the dff with another and tried in game and the guy got white I mean the whole character got white and then remembered tht I forgot to change the txd and then I did that and when I tried to connect to the server it just came up an error all the time so I changed the skin back to old skin and tried but it just came up an error again and after tht I uninstalled the game and then installed it and sa-mp too and I downgraded it but now it comes up an diff error tht u can choose report crash or close
And my GTA is fucked up(singleplayer) every time it's loading to start the game( u know when the music plays ) it crashes and tht happend after I modded a skin but the diff was tht I deleted the original and added the new but this with my sp game happend before my sa-mp crashed and I still could play sa-mp but now sa-mp is fucked up too so can someone help me? pleeeeasseeee I wanna play with u guys

ur saying it came error (with the rasta mod) but how?

idk

the game just closed or what?

It came up an error u know an error when u time out and then the whole game closed
