I had this problem aswell, I started another character, especially after the gibbs blocked task. Have restarted again just a day or so ago, after character would load at all.
Some U have got some highish levels and probs think it would to much to bear to restart, but i only started new character 3 eves ago and are lvl 5 going on lvl6 already and so far, touch wood everythings flowing nicely.
Wouldn't surprise me in rush to get some massive new patch in they'll reset everything like before, so i u think you holding on to somthing, you cud end losing it all anyways.
Dont forget, this is BETA
