Initializing OpenCL runtime for device #1... problem

[amk]

I'm trying to run simple Hybrid Attack https://hashcat.net/wiki/doku.php?id=hybrid_attack

hashcat.exe -m 2500 file.hccapx -a 6 first.dict ?d?d?d?d

but hashcat hangs in Initializing OpenCL runtime for device #1... phase forever.

It uses 70% CPU and loads of RAM. Dictionary contains only 2 words. Any solution?
