DESPERATELY Need Help: How to install older version of Vuze?

[GirlyGirl]

Hi guys,

I really hope someone can help me because this is a serious issue for me.

I'm currently running Vuze 5.5.0.0, but a particular private tracker I'm on requires me to be using Vuze 4.8.0.0.

How do I install Vuze 4.8.0.0 when I've got Vuze 5.5.0.0 installed right now?

Thank you!

Does anyone know how I can go "backwards" from Vuze 5.5.0.0 to Vuze 4.8.0.0?
