Buy the app again from Market?

Hello, yesterday I flashed a new rom on my desire, and when i tried to download some apps that i have bought before, the market shows me the payment screen again.
Do you know why is this happening and how can i fix it??

Thanks

no, but i use my google apps username often(for the same google account), you think that is the case??

Here is what i have done:
I have been using my Google Apps username (XXX@XXX.com) which can be used to redirect to the Google Account that i have on the Gmail (XXX@gmail.com) for the Google services that aren't provided for hosted domains.

The previous orders have been charged on the Gmail Account (XXX@gmail.com) since there can't be a Google Checkout Account on a Google Apps domain.

Yesterday when i set up the phone i used the Gmail username, and after searching those apps it asked for payment.

So, what is wrong with all this? Since the apps are bought in the XXX@gmail.com email, what is the problem with Android Market?

I also have to say that i use market enabler since i live in a non-supported country and faked to the US carrier.

This is really troubling :S

I contacted the support of one of the apps and they advised to buy again and they will refund the previous charge.

Unfortunately this is not a good solution even though it is fair :|

I see..
Well I had changed to the gmail login for some reasons so I suppose I have to buy the apps again :|

Thanks for the reply though
