mr_rodge, my flight school in Florida was extremely meticulous about the accuracy and completeness of information in my logbook and application forms for my JAA PPL license (through the UK CAA) They knew that any errors would cause lengthy delays in the application process.
When I came back to the UK, I waited three weeks before I could go flying, even though I had no issues with my application. I was dying to go up there, but was told I wasn't allowed to do so legally. My friends who did the FAA PPL were given temporary licenses (valid for a couple of weeks) until the FAA sent them their permanent photo-license. Quite a neat idea IMHO as one doesn't want to go rusty, which could affect safety, having just acquired new skills!
I hope your problem gets sorted soon. I would suggest you to ring them and chase up on it.
