how can i do this Im playing the PSO v2 pc game and really want to be able to pay these three quests offline. i tried fiddling with qedit but had no success

(What you are requesting is not worth doing. It would require way to much effort, compatibility issues with the quest formating using opcodes v2 does not support, you would basically need to recreate the entire quest to get it to work on v2 , overwrite files and remove and replace quests.)

Come party with us on blue burst if you want to give more quests like those a try.

well i have blue burst and play on an offline server using thethalli but recently its been giving me problems like its disconecting from the server eventhough it doesnt require internet connection

Aleron Ives has some quests available here: http://psopalace.sylverant.net It might be worth giving them a go.
