After a month of waiting i got my account back.
Sadly my account got hacked some time ago from someone who thought that it would be very nice if he would send an insulting message to someone i didn't knew and also deactivate my account, eventually i had to contact the Deviant art support team and finally with their help i got my account back.
The bottom line of all this is: Be patient with the support team/teams in webpages like this, they got tons of work to do - and also - hackers are there and a good way to keep them away and your account safe is to have a large password in terms of letters and numbers too, sadly i didn't knew it back then and the password i had was quite simple, this was all that this person needed to cause damage to me for his ridiculous reasons.
I am very glad to have access to my gallery again, and even more interested to keep it up to date with works.
Panayiotis.
