Error code 38 on entering cash shop

i got mine to work after cleaning ALL my inventory, i dropped half of my medal(had 28 in inventory), dropped all my untradeable and useless stuff (maple hat, maple gage, some etc item quests, agent suit, etc) emptyed my USE slots, xfered all my chars to another mule, cleaned my ETC, and only had the nx clothes on my equips and a few of other items (like my reverse glove/sword, some medals) and i could go in cs.

transfered 1 item back to equips slots, and started to get dced again, transfered this said item back to my mule, could get in cs just fine.

I just know, i can go in cs if i have nothing on my char, if i ever get 1 pot, or any item that is tradable, i dc lol.
