Plugin cause site crash

Hi,
i installed plugin on my site. At the beginning everything was fine, but when I added dozens of shipping zone (about 60) and, for each zone, at least 2 method based on weight, often the site does not load (blank page) or loads only the header (also in the wordpress administration pages).

Sometimes I get the error of allocated memory:

Fatal error: Allowed memory size of x bytes exhausted (tried to allocate y bytes)

If I disable the plugin everything loads normally.

Is it possible that the plugin generates errors when a large quantity of shipping zones is inserted? How can i fix my problem? This plugin is convenient and is very useful for me.

Thanks for support and sorry for my bad english
