Qsys Error: Failed to elaborate classic module C:/Users/.../yysystem.ptf

Hello, 

i didn't touch my project for a while. 

Now i get the error: 

Error: Failed to elaborate classic module C:/Users/.../AppData/Local/Temp/alt7407_3755802541581721576.dir/0007_sopclgen/yysystem.ptf (254) 

 

In other topics they told to close qsys, quartus and reboot the system but that all didn't help. 

 

I only changed some c and h files on my NIOSII code (nothing related to the qsys) 

Is maybe the quartus installation corrupt? If maybe yes, how to reinstall it preferably (install over the old, remove reinstall)? 

 

Quartus II 64Bit 12.1 SP1 installed 

 

Below the last messages of th Generate log before the error occurs:
