Unable to connect to origin

     I have been having this same problem for so incredibly long and I have talked to many people and nothing seemed to have helped. I had gotten so frustrated and disappointed especially after spending money on the Sims 3 web site and not being able to get my content as well as not being able to install my purchased origin games and expansions. I decided that I would give this a try considering after all I have done and been suggested to do as well as that this was a new step no one said anything about.

     My game is now fixed; no more error message and my content installed and games added. Thank you for thinking "outside the box," unlike the routine answers I had previously and continuously gotten. Many thanks indeed!

clear the IE browser history and reset IE to factory settings.

I have the updated version of origin and its still saying the same thing

OMG!! Thank you so so much.  This fixed my launcher!  In my downloads folder; there were two email address files showing.  

• I removed the file labeled with my old email address that I was no longer using for Origin or The Sims 3 from the folder entirely.  

• I cut my long number file that contained both the files labeled: ChallengeData and Passport Data and moved it to my desktop.  

• I cut every file containing the words dynamicchallenge, BIN and the FSI View Count Tracking File from the downloads folder and put them into the folder I had previously cut from downloads and moved to my desktop.  

• After I had made sure I grabbed all files; I moved the new long number file back to my downloads folder.  

• I restarted my launcher and for the first time in a year;  

NO MORE ERROR MESSAGE!!!!!!!

I almost fell off my chair I was so excited.  It worked.  This is the solution.  I did change my email address.  Thank you so very much!  Origin now shows that I played The Sims 3 for 6 hours also and it wasn't showing that I even was playing the game anymore.

My launcher not telling me that it is "Unable to Connect to Origin" is a huge lifesaver and a blessing!  I can't thank you enough!

Hey so my Sims3 launcher wont let me log in, I have deleted cahed data from both IE and firefox, removed the FSI and .bin files and my email file and am about to restart my computer, I really hope this works. I also removed the 2 folders that were named a long number, and put them on my desktop in case they were needed. But what "new" long number were you referring to?
