roll 20 won't launch

Ive tried for several days to log into roll20 and i can log in but when i launch a campaign this is the error message i get from the log: event.returnValue is deprecated. Please use the standard event.preventDefault() instead. any ideas on how to fix this or correct it

Please follow all four steps on this page: <a href="https://wiki.roll20.net/Solving_Technical_Issues" rel="nofollow">https://wiki.roll20.net/Solving_Technical_Issues</a> If the first three don't alleviate the problem, a full copy of the log should help give a clearer picture as to why the issue is occurring.

i followed those instructions and it didn't work..here is the whole log: Consider using 'dppx' units instead of 'dpi', as in CSS 'dpi' means dots-per-CSS-inch, not dots-per-physical-inch, so does not correspond to the actual 'dpi' of a screen.

Thanks for the console log, Rod. Would you also mind going to <a href="http://supportdetails.com/" rel="nofollow">http://supportdetails.com/</a> and pasting the results here (without the IP address, please)?

when i try to join any campaign, either one that i play in or one that im a dm in. it starts to log into the roll20 campaign and the screen stays black and never logs into any campaign. it freezes on the 2nd phrase( the funny little sayings that appear on ur screen when you are logging in).
