Error using Materials API

Dear Mr Nishihara,

I tried to look up for materials using the Search bar, but it keeps giving me error. When I first used BURAI, there was no problem, I could use it for MnS and PbS. But after few days, it started to give me error. I tried to delete everything and re-download again, but it's still the same. I use Windows 10 on HP Pavillion laptop.

Thanks.
