Shop keeps disconecting me

I'm not sure if someone posted this already and if they did I'm sorry. I'm able to enter the All-In-One shop, but when I try to open an actual shop, like swords for a warrior or armor for a bowman, I disconnect. I can't buy any equips without this happening. Do I delete everything and re download the client?

When you downloaded the SnailMS client file (which should be a .rar), you would have had 3 files that you were to paste into your v.62 Maplestory folder. If you only pasted the SnailMS client, then you need to paste the other 2 files as well. Make sure you replace the files that's already in the v.62 folder.
