Malfunctioning on I-TASSER and COACH servers

The I-TASSER server read wrong my sequence in two ways:
either combines the name with the protein, i.e. I send
>MyProtein
DVHGSITKLN
and the server refers that I sent the sequence MYPROTEINDVHGSITKLN
or it simply refers that my sequence is not of 10 aa at minimum but actually that is the lenght.

The other error have appeared me is with the COACH server, the problem is that it do not recognise MyOtherProteinRefined.pdb at all, giving that I have downloaded it in past days from the I-TASSER itself.

I do not know if that is because I have sent about 20 sequence along past month and it means that one user is overloading your servers. Just tell me that, please; perhaps I could remove some previous work in order to free space. I need to finish this work for publication, thanks for your understanding.
