upgrading storage size

pojeda

Hi,

I find Zotero very useful. Because of that I decided to
upgrade the free 300Mb couta with 4Gb (I thought it was
possible). Then, I purchased 2Gb twice. However, it seems
that I purchased 2Gb for two years and not 4Gb for
one year.

Can I have 4Gb for one year?

Regards.
