Hi, I've installed the Silverlight Video module but whenever I try to upload a video file, I get the below error:
A critical error has occurred.
"Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."
Do I need to grant permissions to a particular directory? I'm able to upload other video files (via the Media module). My site is hosted on GoDaddy so could their settings be causing a conflict? Below is part of the Event Viewer message for this error. Thanks for any suggestions.
"InnerException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

| The Silverlight video module is trying to upload the file to the DesktopModules directory not the Portals directory where you would normally upload a file to. So that is why other videos would work and this one would not. |

I am having the same problem. GoDaddy deluxe host account. DotNetNuke is at 4.8. My DesktopModules and Portals directory have the same permissions, Read and Write. I can also use the Media module, but sure would love to have the Silverlight. First I wondered if DNN 4.8 was the issue, but I see other forum users can work in 4.8. Above I see the issue has been around since November 2007. I am also working with Godaddy on a weather module that does not have correct permissions 'The permission problem is like the one when IIS is serving from a networked attached drive'. Do you anything I can test to figure out where the problem is?
The Stadard DotNetNuke modules seem to all run with my GoDaddy hosting account. Half the free modules I have been testing this week are having problems. |

| I have nothing to test the permissions. Basically if you get the error indicated in the post it is a permissions issue. |

| I created a local DotNetNuke server and all is working on my local machine. The Godaddy server is still having permision problems with your DNN module and others. I will probably harden my local machine and use a the public web server because it works and GoDaddy has not. |

maybe is beacuse your hosting is with medium trust.
i could resolve this in the album case, but i guest in the video is the same
1.- create a "videos" folder in ~\DesktopModules\SilverlightVideo
2.- in "SilverLightEdit.ascx.cs" comment the method call to EnsureDirectory(new System.IO.DirectoryInfo(path)) or just simply delete that line
