I currently use SVMS Platinum 6.0, and when i first installed the program everything was working fine. one day i was playing back a project i had been editing for a long time and i received the message " An invalid device was specified" and under the "details > >" button was " The playback device does not support the current output format.
The playback device does not exist." Even when there is no media on the timeline, whether i push play, pause, etc. i receive the same message. Possibly a problem with codecs.. but im not the best with computers.

Any further information needed to help, please ask. I'm not sure what iformation i should give out to better help someone help me.

Thanks in advance,
a very frustrated individual :(
