When I updated to the latest version of this script, I wouldn't run anymore.

After some initial investigating I got the following error in the error console with Scriptish (GreaseMonkey wouldn't show the error):

[oujs.orgscriptsstats@httpuserscripts.orgusersburn] SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data oujsorg...user.js (line 27, col 2)

My guess is that it has something to do with existing data stored from previous versions.

Re: @jerone:

Hi thanks for reporting the issue. You're right, it is due to invalid JSON format. Will publish a new version as soon as possible.

Re: @jerone:

(hopefully) fixed with v2.42

Confirm running again. Will check later if it actually counts.

Counting up (sum) confirmed working.
