Critical error receiving profile data

Thank you for reply. I poked around earlier with ctrl-F trying to look those keywords in profiles but i didint think to use the word "null". Doing so led to odd lines followed by null but eventually i arrived a "null" in a line followed by the "salessum", turning that to 0 like you advised fixed the problem and i made it into the game without error and even faster than ever before (reduced loading time). No idea why the problem happened in the first place, my guess is that the game lagged or rather had the loading icon rolling while i tried to put item for sale in flea market. It did put the item in the flea even tho it showed that no items of the kind were in sale to begin with ( MDR 7.62x51) and after that i noticed that the game is stalling with the loading and just alt-f4. after that the error occurred but its fixed now. Thanks alot!

On a side note i did change remove some flee blacklist items in akiconfig mod that one of them was the dev_balaclava which after investigation seems to not exists in the first place so maybe that also was the cause. changed everything back the way they were prior the error in hopes that it fixes the source problem.
