Still no solution, but here's what I think the problem is (I'm not 100% sure this is what's actually going on, but given my understanding of how the PSN works, it's my best guess):
Every PSN game has a hidden version number associated with it, which is increased every time the game is updated. So, when we first released flOw back in 2007, it's version number was 1.0. Then the expansion pack came out and increased the version number to 2.0 (I think the real version number is something more complicated, but you get the idea). Quite a while later, trophy support was added, increasing the version number to 3.0.
Now, when you first booted up the game, you may recall that it told you that it was going to download an update, which happened to be the version 3.0 trophy patch. After installing that update, the version of the game sitting on your hard drive becomes 3.0. When you then try to install the expansion pack, the installer compares the version number of the game on your hard drive (3.0) with the version number of the expansion pack (2.0) and decides your version is newer. That's when the annoying error message pops up and the installer quits. This same problem happens to people who pay for the original game if they play it before installing the expansion.
There is a workaround for people who have purchased the full game that unfortunately doesn't apply to people who participated in the Feb. 11th promotion. If you purchased the original version of flOw, the PSN store keeps track of that, so you can just delete the 3.0 version on your hard drive, re-download the original game and then immediately install the expansion before the trophy patch has a chance to be downloaded. Right now, it looks like the store isn't keeping track of people who participated in the promotion, so please don't delete your game to try this workaround, you won't be able to get it back!
Sony might still be able to fix the problem by either updating the version number of the expansion pack to something higher than 3.0 (which is unfortunately quite a bit trickier than it sounds), or making it so the store somehow remembers who downloaded the game during the promotion. Unfortunately, neither of these solutions my be possible, so there's a chance the free version of flOw (once updated with the trophy patch) will never be compatible with the expansion pack.
Luckily, we've invited the Sony producer for flOw to sit with us at next week's Game Developer's Choice awards, so I'll be able to ask him about the problem in person.
Again, thanks for taking the time to try out the game, and so sorry for all the trouble.
