get the massage:

"The MainConcept MPEG plug-in was not able to intialize
properly. IT appears that some modules are being used from a
folder other than the install folder.

Most likely another third-party appliction has installed
MainConcept modules in the ayatem folder. These may conflict
with this plug-in."

because of that - saving is impossible.

Do someone know what to do?

Many thanks in advance.
