I saw this error on a broker that changed their symbol names. I had to update my charts to the new symbols. But if I accidentally open an old profile that uses the former names, the charts never update, showing the "Wating for update" message forever.
In the Market Watch, I can see the true symbol names, and if I drag the new name onto the old-symbol-name chart, it works. E.g. the old symbol was "EURUSDpro", but the equivalent new symbol name is now just "EURUSD".
In your case, you're not changing profiles, but just changing accounts.
Are the symbol names identical for the two accounts? If not the same, that's the problem. If the same... I have no idea. Good luck.
