Error code 38 on entering cash shop

I dropped all the things that I can drop. Transfer out everything that can be transfer. still doesn't work for me.

I dont want to drop anymore of the untrabable items that I collected over the years. I'm just glad that it happened on an account that's already reach lv 200 and basically has no use to me. (although I do still want to gach for the chairs that's untrabable >.<)

I'm just gonna wait until they fix this problem and if not then o well.
