Okay so this has been written in one of the sticky posts in the bots section:
"What the hell is a L2Info.dat?
It's inside IG Walker folder. It contains all the info the IG walker shows ingame. The IG Walker do not read your itemname-e.dat to list the items on ground, for example, it has an internal database to show it. That's the reason why custom-made items (like in many private servers - like mana herbs, gold bars, whatever) show in white on IG Walker, it doesn't have that item on it's database and consequently, it will not show on any listing of items. This guide is NOT to fix that problem. At least not yet as I haven't found a way to do it."
So i suppose the problem with the blank walker settings is caused by this file. But... what i did was take the l2info file from a walker that i used on my windows xp and i know worked for the same system folder and the same server(the only difference is the operation system and the version of the walkers) replaced the IG OracleL2Walker 2.17f L2info file with the "working" one and yet when i logged in the settings were again empty.
Edit: I tried the out of game walker and it works flawlessly verifies, logs in, skills and items are all shown. So i tried to copy the OOG L2infoB.dat to the IG folder but once again it didnt work. I don't know what to conclude anymore seems like it was all wrong :S
