Why I could submit succesfully with FF 4.0 and NOT with FF 3.0?

I have just tried to submit a filter I have made with FF 4.0 that is based on the stripes theme, and I have used my own original account and surprisingly I have been able to submit the filter succesfully without any problem.

So it seems that the problem is NOT with my account, because I have been able to use the FF 4.0 with my account and the same submit server, so my account is working right IF you use FF 4.0 unless there is a different server for FF 3.0 filters and another for FF 4.0

So then, how is possible that I can submit without any problem using FF 4.0 and my account, and I can´t submit any filter with FF 3.0 with my account, but I can submit with FF 3.0 with a new account.

FF 4.0 + my account : Sucess
FF 3.0 + my account : Not possible with any filter
FF 3.0 + New account : Sucess

If you want to see the filter to see why is giving the error shown above, I upload it here for you

Will try to submit the other filter and see what happens

I have been able to submit two new filters now using filter using FF 3.0 and my own account

should I try to submit the stripes filters?

It is broken, though your FF 3.0 doesn't display this as a problem — but the server-side 4.0 rejects the filter.

Well, the situation is clear. While we're fixing it you can lower the Max value of the IntSlider (as shown on the CFandM's screenshot) and submit the filter.
