First of all I'm very sorry for delay in replaying you...
In any case it seems you were informed by the wrong way because there is no need to purchase anything and certainly it's free!
You should simply visit our site http://www.elecard.com/products/products-pc/consumer/mpeg-player/
On this page please find the words:
"If you have encountered issues with Elecard MPEG Player 2.3.2 and lower.." You need uninstall all versions of Elecard player below 4.0.2 then download, unzip and run Elecard MPEG Demultiplexer Patch installation to fix the issue. "To download the patch click here" (http://www.elecard.com/ftp/pub/mpeg/player/Elecard_MPEG_Demultiplexer_Patch.zip
