Hi Jay,
For 5.2.5 compatibility, you'll have to stick with Figure 1.2.1.
You'd need to upgrade to 5.2.6 minimum to install a newer version of Figure, which will enable you to install Figure right up to 3.0.0, though with some of the later features not taking effect (look-up tables, fonts).
The 5.2.5 -> 5.2.6 being a minor version bump, this should be a painless upgrade. cf
