Subject: API - getCandleData errors, portal login problems....

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.
