Install Error

On a Joomla 1.5.7 site running in legacy mode the install failed. The .tar file is 1.75 meg and appears to be ok. I've installed Mobile Joomla on other sites (prior to this "final" version) and it has always worked fine.

MJ was tested in J!1.5.15+, so update your Joomla to latest version (for 1.5 branch it's 1.5.25).
