Hmm, I found out a solution... It is create a diff, I found this out in a Dutch Official Ragnarok forum.
There are many incorrect scripts and we need to make a diff and correct it.
But, the method need too many requirements like download large files...
By the way, not just like that, the process is very hard and complicated.
I wonder before they know create diffs, I heard that there is another two method which is more easier.
One is what I'm waiting that who know it. (I don't know)
Second is JUST WAIT THE NEW PATCH!
... But I wonder is anyone NOW! patches? If anyone patches NOW! (Well, already 3 days after the lastest Sakexe.exe patch) Cannot patch too? But I'm very sure, this will not be only me, because what I saw in the Ducth website is... THERE ARE TOO MANY PEOPLE WHO SUFFER THIS ......(How to say... My English is not very good, but I think you all know what I'm going to say)
So, this is not a normal problem, I will keep wait for 7 days, already past 1 day in my country... after 7 days... lol, if no new patch out, I will just have to follow the diff method. (I hate long and complicated processes! But there is only a way to play RO. There is an idom, which is not English's, it is "We must suffer before we get happiness". So need to get through the method in order to get happiness (play ro)
