Hi,

Our software connects to your API so our mutual clients can get streaming quotes, charts, etc. Has been working for years. Now there seems to be a problem

Issue 1:

Client login and streaming quotes work. but getCandleData with same token/headers returns

{"success":false,"message":"Invalid API Key","errorCode":"AG8004","data":""}

this is for code that has previously been working fine.

Based on some searching, was suggested to regenerate the API key, but

Issue 2:

when I try to login to the API site with the login we had “mike@medved.net” it seems that you have changed the login procedure and that is no longer a valid login. I tried to register a new account but there is no way with a US mobile #.

Please advise on both issues.
