Game crashes after logging in with an options character

[R3D5KU11]

Details: I have an item/items that cuase my system to crash every time it is viewed from my inventory, whether by going to items or trying to transfer to mog safe/sack/satchel etc... I purchased several Guisarmes from Altepa [A] and planned on selling them for gil. This is when I first began starting having trouble with the crashes. Every time I try to sell, view, transfer the Guisarmes in any way my system just freezes, and I have to shut down and start back up again. And it seems like it happens as soon as I put the selecting cursor over it, so I'm not really able to actually do anything with it.
Steps:
1.Open inventory
2.scroll down to item (Guisarme)
3.System freezes
