Old SC upgrade

Post by _Tom_ »

Hi,

I have an old SC (2007 :)) that stopped working with the new version of win (on the viewer part) - it connects but the screen is gray. The viewer starts with an error stating - the specified system semaphore name was not found.

I am trying to update with the SC online creator but to no avail...I have made a new rc4.key and included the old files, but the returned SC is blank - without server.

The instructions are somewhat scarce or I am just getting old ;).

Any help will be appreciated.
