I am sorry to hear that you are having difficulties.
Usually those types of difficulties are temporary due to heavy server load or other temporary issues.
Just so you know, you are on the Chopin sever - not Starka.
The only way to possibly change servers would be to terminate your account and then sign up for a new hosting account.
However, even by doing that, there is a chance that you would end up on the same server you are on now.
