ic24.net webmail

[#1]

I'm unable to login to my main ic24.net account although a 2nd account is fine. I've checked all the setting with the working Ac and there's no issue there and password is correct. This is the first problem with it in 20 years and I thought it bomb proof.
All help most welcome.

Update.

It seems my ic24.net Ac went down at about 23:00 on Monday 11 November and coincided with 3 e-mails being sent from a Gmail Ac. 2 mails arrived the 3^rd didn’t, making me think the Plusnet mail server found something bad in that mail and de activated my Ac.

I have also found I’m not able to up date my website also linked to my main ic24 Ac. Clearly that a major problem as I run a help group for pensioners from it.

Is there anyway I can re activate my account or do you know anyone who can – this is now mega urgent please help.
