stuck notes in GPO playback as Dxi

Hello to anyone who can help me with this one.
I am using Garritan Personal Orchestra, and I'm using it as a DXi, I can't use it as a VST as the certain files that handled that have been removed on purpose, as I could not access the controller pane and change values etc with midi imported files for playback through GPO.
I'm getting stuck notes when there are long notes held over a tempo change, and the solution on the GPO tutorial page is to put another note after them, and make it silent. This works sometimes, but then in another orchestral part, the stuck notes then start happening there instead. I came across something on an internet search saying that apparently this is cause by some kind of looping with midi information, and one solution was to turn the "Midi Thru" off. But I cannot find anything in the Home Studio where there is an option to turn the "midi thru" off. Probably under a different name for the same process, or just not there at all.
Does anyone have any idea how to fix this?..and yes it IS on the places where there is a change in the tempo, I switched to the tempo view, and sure enough, when I played the midi score back, that's where the notes got stuck.
any ideas? I'm hoping that someone out there has solved the same problem.

It's a known bug but not of GPO DXi but of Cakewalk and other sequencers because of the way they handle MIDI for Note On Values of "0" sent when releasing a note, instead of the expected Note Off message., so far nobody at Garritan really has addressed this but besides using the VST versions , there are other workarounds you probably want to take a look in here such as the MIDI fixer and adding notes. I own a copy and have the VST version that for some reason crashes on my system so I only use DXi

Sorry, but never tried GPO studio. I always use it as a plugin in SHS.

Try this: Download this program (it's a VST host, for free) and after installing it, try loading the VST version of GPO. If it doesn't work, then there are some conflicts with the GPO installation process or due to whatever you have done with the installed files. You might need to uninstall GPO altogether and re-install everything including VST and DXi versions (provided you have a legal copy of it).
