Try deleting the dayz folder in the /documents folder. It worked for me.

There are other items as well. A Hunter jacket now weighs 5 kilos empty. Assualt vest is 6 kilos empty. A medium tent (the blue festival type tent) weighs a whooping 25 kilos (should not be more than 1-2kg), a pair of BDU pants is 3 kilos, walkie talkie is 5 kios with a battery in it 1 kilo without battery, a KA mag is 1 kilo, while the M4 mag is 0.25 kilos a piece. A tactcal helmet weigs 1 kilo, but add a 0.25 kilo flashlight to it, and it weighs 3 kilos. A school back pack weigs 5 kios empty...the same as a mountain back pack etc
