Hi. I'm using win 7 and I have 4 x RX480 8gb cards. When I create a bin file, it will list this:

[20:10:39] Started sgminer 4.1.0


[20:10:39] Started sgminer 4.1.0
[20:10:40] Kernel chaincoin is experimental.
[20:10:40] Error -11: Building Program (clBuildProgram)
[20:10:40] C:\Temp\\OCL5432T5.cl:79:10: fatal error: 'blake.cl' file not found
#include "blake.cl"
         ^
1 error generated.

error: Clang front-end compilation failed!
Frontend phase failed compilation.
Error: Compiling CL to IR

[20:10:40] Failed to init GPU thread 0, disabling device 0
[20:10:40] Restarting the GPU from the menu will not fix this.
[20:10:40] Try restarting sgminer.
Press enter to continue:

When I have an old bin file it's okay. But when I want to mine a new coin and I do not have a bin file I have this problem.
Does anyone know what to do ? Ths.
