Can't switch to Sphax 218x

[MrSmartyPants]

For some reason I cant switch to the recommended version. I click on the resource park and it doesn't change or crashes, it just doesn't change. I gave minecraft fore ram and it still doesnt change. I also have mods installed.

Can you try to open the ZIP file and read the first TXT you find in please?

I you can't open ZIP or read the TXT, your downloaded file is probably corrupt and you must redownload it.
