Client with l2 walker? and other things lineage 2 4k resolution

Morning to all

I have few questions

1st I just downloaded the rpg client and i saw inside OOG l2Walker ( that means that i can use l2Walker??)
2nd  I did the update and when i tryed to open up second client to buff my char i was getting critical`s
3rd   I cant start the game from the Hot Fix icon ( it`s working only with the updater, and every time i have to do Check  Files to let me use the Start Button)

Anyone has any clue about these 3 things?

Thanks in advance

that walker is for "offline" shops. there are no decent off shops u can only make a shop with that walker and u cant do anything else with it its pretty much "castrated".
i dunno about criticals
what is hot fix icon? i launch the game from system/l2.exe... it works fine for me and i dont have to update everytime


OK about the l2Walker
The critical`s are happening when i try to open the 2nd client ( until the new update i could open 2nd client with no problem)
The Hot Fix icon is the yellow glass  and it`s opening the rpg client , without the updater.
Allready tryed to open from the system/l2.exe with the same result`s  with critical`s.

you should try redownloading and reinstalling your client if that does not work you should post a screenshot with and error. the problem must be on your side. post and error screenshot
