"File is null" although "shaderlog" is present

I don't have that version to test.

It could be due to your emulator Path being enormous (L:/ROM´z ( GAMES ) FOR EMULATORS!/The ROM´z COMPLETE!/rPCs3 - Working SONY - PlayStation 3 - PS3-Emu_v.0.0.5.Neueste !/). Although this isn't a common issue, try placing RPCS3 folder on L:/RPCS3 and retry.

If it works, it means your path is way too big, you need to rename folders, use smaller names or use less folders.
