Try uniting the center pin and your metal layer and see if it works. If your structure works in this case, it may a be geometry issue. But you can simulate with the center pin and the metal layer united.

try to check the HFSS project and temporary files paths. Try to rename it in a simple manner.
Sometimes white space and national characters could cause such a problem.

i am sorry ,does what your said can cause the error, are you sure of that ?

Yes, very often programs can't store files in a folder with unicode pathname.
It's requires correct code writing and use a libraries that support unicode.
I'm not sure about HFSS but it could be...

check also that your temporary drive is not full

Also, such problems sometimes appear due to some problems in the license server, may be you need to re-install HFSS
