If you still have access to PlayStore it should be easy - since you already paid for it you should be able to re-install it for free.

It does not show up in the "My Apps" section. (FTR: I don't have a paypal account, so I must either have purchased it via Google, or never bought it.) But I also cannot find any other option to change the LED colour, nor any mention that this had, at one time, been a non-premium feature. Did you?

[Edith says I should mention that Titanium Backup 'remembered' I had the Pro key, and behaved accordingly upon re-install after the Cherry/1.6 repartitioning wipe.]
