I was thinking that I could just delete the .DAT file that is downloaded when the launcher begins, then when this patch is done, I will reload all the data fresh. Problem is, I'm not sure which one to delete - I opened explorer and looked at the .DAT files:
client_highres
client_portal
client_cell_1
client_local_English
If you know which one is the right one to delete I believe this could solve my problem.
