This is when I'm searching my address on the page you linked to. Exactly how many blocks have I contributed to, I don't know, I can tell you that the confirmed reward is 1.81BTC, with another 0.43 unconfirmed.
First seen?: Never used on the network (as far as I can tell)

Note: While the last "balance" is the accurate number of bitcoins available to this address, it is likely not the balance available to this person. Every time a transaction is sent, some bitcoins are usually sent back to yourself at a new address (not included in the Bitcoin UI), which makes the balance of a single address misleading. See the wiki for more info on transactions.
Since your problem is resolved, are you able to see your history now on http://blockexplorer.com/
? Because i do have a balance, but if i put my address on the blockexplorer.com i have the same output from it as you did...
