error::Not found Haxe.io

i just got an update to latest version, and i got this error

C:/HaxeToolkit/haxe/lib/lime/7,3,0/src/haxe/io/Bytes.hx:793: characters 76-92 : Type not found : haxe.io.Encoding

Are you perhaps using an old Haxe 4 preview build? You might want to update to rc.2.

In order to fix issues we were having, we currently support Haxe 3.4 or Haxe 4 development versions (but not previews)

(minor correction: Haxe 3.4 or 4.0.0-rc.2 - release candidates are different from nightly / dev builds, you don’t need a nightly build)

Sorry for late reply. thank you guys, I will double check it as soon i get back home.
thanks.
