Articulate STOPED WORKING

Hello everyone...

Well, I have been working with Articulate Studio Pro 09 - Update 5 and everything was good until yesterday...

I might have done something wrong but I have no idea what the problem is but Articulate just stopped working.

I get a message, when i try to open it... I have install it over and over and nothing...

When I'm running installation I get installLicense.exe error and after the installation nothing works.

I looked for a solution and saw something about runing gpedit.msc but my windows 7 home premium doesn't have that command.

I'm in the middle of several works and going crazy...

Something else happened. I have some published files that worked perfectly (launch_presentation.exe was working) and now they don't work, nothing shows. But when I open player.html every thing works.

If someone has any ideas I would be much appreciated
