Keil µVision IDE interface problem

Hello, at the begining sorry for my English. I have a problem with keil interface. I reseted my computer and i installed keil uVision 5.29 back. 

As you can see the codes are not colored as  before. I have no problem with compiling also i can upload my codes to my board (STM32vldiscovery) and it works.

But i can not focus coding in this situation. If you know about it pls let me know. Thank you!
