So basically what its saying is with 4918 RAC in team GRC, we require 806,996 coin age.  But in your purse you only have 32 total coin age.
You would need at least 4,030 coin_age (roughly) to earn more than 1 bbp in the leaderboard (IE .005% of the gsc contract) so you just need to increase your coin age.
If you send yourself a couple hundred K of BBP into your CPK that should fix the problem.  Then the .99 coin_age_percent required would drop to something like .50.

Then the sendgscc will work.
