Without tab bars in the sublime text editor 3

[Hans]

Hi!,
I downloaded ST3 with payment and got a** unregistered one without any tab bars** in the above part of the screen(working area). So, I cannot do coding and saving it in the file. Anybody can help me to solve this problem? Much appreciation in advance.

Platform? OS? Can we see a screenshot to better understand the problem?
