Project refuses to export.

Having trouble with LMMS? Ask about it here.
I do not know why, but every time I attempt to export my piece, the sound of whatever bar it is on starts playing for a very short period and then the export window crashes. I have had this issue before and have solved it by closing all open zynaddsubfx windows. Unfortunately this fix does not work on my current piece. I am uploading my project with the export problem so you guys, if you possible, can maybe take a look. If anyone can help I would be immeasurably grateful.

Edit: There are some vsts in this piece but the glitch still happens when they are removed so just ignore them.

Done

You have a time-signature change after 8. bar. Here the project shifts from 4/4 to 5/4. Is that intended?
If yes, then You need a 'smooth' change, meaning you should use a curve with at least 3 points. However this issue is solved in RC5, and you should be able to export with the RC5, also with discreet ts-changes -try either :')
