I’ve found a fix, as many people have been mentioning, simply add the file to your “Trusted Locations” and then open it. For those who need a detailed explanation, continue reading:
Right click when you see the “D’oh” error and select “Global Settings.”
If you are stuck on a blank white page, make sure you are actually opening the downloaded swf file with adobe flash player (actually finding it on your computer and opening it through flash, not copying and pasting the appspot url like you’re accustomed to). You can also drag & drop onto the flash player. You can download the file here: https://www.realmeye.com/wiki/using-the-adobe-flash-projector.
Something like this will pop up after right clicking the error page.
Select the “Advanced” tab and then click on the “Trusted Locations Settings” button. Next, click on the “Add…” button.
Something like this will pop up. Click on “Add file…”
Click on “This PC” or “My PC” and select “Downloads” (IMPORTANT: This will only work if you’ve downloaded the most recent swf file onto your computer).
In my “Downloads” folder, you can see I have the swf file ready. Open it and press “Confirm” or “Ok.”
You should see something like this listed.
For example: C:\Users\C_l_l\Downloads\AssembleeGameClient1516122971.swf
Now, go to your flash player and under the “File” column, click on “Open” and then “Browse…”
Go to your “Downloads” folder again and open the same file
If this works, please let me know, if not mention me and I’d be glad to help.
