Ye' are not required on sayin' anythin' in the e-mail though if it will grant ye' ease, ye' can provide a reason.
Waitin' for the registrations to re-open to check if yer account was properly activated depends on ye' instead of I. If ye' really would like to confirm its activation, then waitin' would be the best bet. There's a chance the registrations may not open early in the morn like they have done recently. There are times it opens durin' the evenin' hours or even mid-noon. Ye' just have to be patient.
I mind not the questions ye' ask. Feel free to question further if ye' are even more confused over the matter.
Not very sure as to why it does that, but I do hope you can find a solution since I have not have this issue before.
