I have just bought and installed MMM 2013 Premium through internet and installed without problems. I have also Music Maker MX Production Suite installed.
After the installation and running for the first time, it hangs when "initializing soundpool". I have left it for 2 hours, but no changes. MX Production Suite works without problems.
I have the soundpools on a remote folder and I have a lot, but as the program didn't initialize, I didn't have a try to tell it where they are. It hangs the very first time. Tried rebooting without changes.
Specs:
Windows 7 Home Premium 64 bits. Intel Quadcore. 8 Gb RAM. Nvidia GTX 460.
