Same here. I spent the best part of a day last week trying to fill in the on line application for a 60 day tourist visa for our upcoming visit in Jan.
I wont go into all the details, but let's just say it was one of the most frustrating things I have ever tried to do. In the end I decided to trow in the towel, and will get an extension on the 30 days on arrival. Another friend had the same problem, and also gave up with the bloody thing, and is having to make a trip to the nearest Consulate to get his. This fiasco is in complete contrast with my experience in obtaining my E visitor visa for Australia, that was approved in two days, took 5 mins to complete, gives multiple entry's in a year, and was free!!!
