KMS Update Failure~

hi ,i was updating kms ver 1.2.164 yesterday,

but my internet connection suddenly broken,so the auto update was closed .

let me sad is i can not update anymore.

i use win7 operation system.

it said the program can not run.

i am afraid to re install the game again.

because it is large files and waste me a lot of time.

anyone know how to fix the bug?

hmm in GMS whenever my update breaks the maplestory folder creates weird files like

jsaodi^%&)% folder
djasdas!@# folder
asd213891ad folder

those are temp update files created during a patch
delete them and reapply ur update
