The only one thing that I can think of that might cause a problem with the update to
WM Recorder 12 would be... Not having a current version of WinPcap. Version 4.0 of WinPcap Might help you out.
I think WM Recorder 12 is a solid program and also
Replay Media Catcher version 2.10 is rock solid aswell.
Hope that helps.
