It's too large. max size is 80 x 80 pixels, yours is 68 x 92. I resized it to 87% of original, however it's messed up the writing similarly to the forum compression.
You'll probably want to erase and rewrite, therefore I didn't make the outline transparent again. If I can assist, please give me a shout.
(oh, and I didn't even TRY to re-write it, as I SUCK bigtime at that)
