Kindly I ask your attention.
Could you be se kindly and update your question with which Operating System (like Windows, Mac, Linux, etc), x32 or x64 OS, browser, browser version you used and x32 or x64 and which Adobe Flash Player version and type you have installed?
Version is like a short/long series of numbers with or without letters like: 11.1A or 1.11.AA1.1000.
Type is x32 (x86 or 386/586) or x64.
How to find out which OS:
And watch if it's a Beta version, these versions are update version, but not fully tested. So, Always go for the Stable version, unless you want the Beta version for a try and help the developpers.
Start/My Computer, click right on it and choose Properties. Now a window will open, here you can find the Windows version you have installed and/or not with Service Pack, you can find at System Type which x?? version you have installed.
How to find out which browser:
Start your browser, go to Help or Extra or Over. Here you try to find Over, click on it and have a look at the next screen. Here you can find the browser version and when there is no indication about the x?? type, you could do the next:
Start/Programs/Folder of browser or Shortcut. When a folder, look in the folder for the shortcut. Right click on the shortcut and than click Properties. Here you can find the distenation of the shortcut, when it says Program Files, it's a x64, when it says Program Files (x86), it's a x32 type.
When you have these information updated, we could search more accurate and mostly will find the best answer when possible. And you could use the same information to take a look on the net yourself, when you found the answer, please notefy it here with the full answer yourself.
Start your browser, search with different search engines and use different phrases:
Some times a Black Screen while opening a .swf file
Black Screen while opening a .swf file (browser name and or Flash Player)
Hopefully I let you known enough, that you will find the answers you seek!
