Error using Binance.us API

[rflsierra]

Hi, I used this library before without issues, but lately, I have encountered some issues. For example, when I run binance_ping(), I get:

Error in if (BINANCE_WEIGHT > 1159) { : argument is of length zero

At some point, I got a message related to eligibility, and it took me to the binance.com site (I haven't been able to replicate it, sorry), which made me think it is a binance.us vs binance.com issue.

I tried modifying the code locally and changing the API URL to api.binance.us, and now I get a new error:

Error in config() : could not find function "config"

I assume there is something going on since binance.us started having issues. In any case, is there any guidance you can think of to correct this?

Thanks!
