After the latest Windows update June 10, I get the “could not connect to simulator” error message. Any suggestions? ---

Hi …, Lets start from scratch with latest Simlink . Please disable any Antivirus and Firewall. In _Simlink Plugin Settings_ uninstall Simlink plugin from each FS, then completely uninstall Simlink using Windows Programs and Features exactly as under. ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/2X/c/cf5a0a5b707969d9ca0b36eaa5e903813457a2fa.png) If they exist delete directories c:\Users\username\AppData\Roaming\Navigraph\Simlink and c:\Program Files\Navigraph\Simlink Then download and install latest [Simlink](https://navigraph.com/account/downloads/simlink)using the default prompted locations. If you are still experiencing problems please post screenshots of Simlink Status and Simlink Plugin Settings pages using [Guide to posting Screenshots](https://forum.navigraph.com/t/posting-guide-uploading-screenshots-or-images/116/2) If still an issue, please post latest c:\Users\username\AppData\Roaming\Navigraph\Simlink\logs\simlink\_xxxx.dlog Cheers Ian ---

Ian, Thank you…but now I have a new issue…Simlink rejects my username and password even though it is the same credentials I use to sign in to this forum and to my simbrief page. I have tried to reset the pw several times but still no luck. ---

Please check the usual caps lock, no special characters etc, restart Simlink ---

Still not able to login to Simlink. It appears that the stumbling block is this: “[Simlink.auth.us-east-1.amazoncognito.com](http://Simlink.auth.us-east-1.amazoncognito.com)” (I can log in to My account at Navigraph etc. no problem) ---

Does restarting your machine change things? ---

No, it has been restarted several times and I have even reinstalled Windoze 10. The simlink also offers to sign in using Google and that gives an error message about not being authorized…. ---
