When i enter  Physics:-Version() I see the output

The "Physics Updates" version "859" is installed but is not active. The active version of Physics is within the library

   C:\Program Files\Maple 2020\lib\maple.mla, created 2020,  March 4, 20:36 hours


I tried to install it using Maple Cloud. The installation is stuck as seen below. Also i deleted the text file in the toolbox 2020 folder, maybe in the hope of starting from scratch.

Can someone please explain what to do to manually add the physics update, step by step. I am not that computer savvy as some of the users appear in other posts , I did try reading some.
I tried to download the physics update manually but I keep ending up with the same maple worksheet that says you need to use maplecloud.

In case you cannot read the text in the image

I notice that when I enter ?convert or ?convertininto the maple prompt, the help window opens once and then ceases to function.

Update. It seems that the problem is not restricted to a specific command, this occurs for any command. To replicate, open help using F1, exit maple help, then open help again using F1. Maple help won't open again. I have to do a hard exit to get it to work again.

Platform details:

I would like to factor an algebraic expression that contains exponentials.
Maple spits it back unfactored. Did I enter it wrong?

factor(exp(4*y) + 2*exp(2*y) + 1);

I would like to factor


which I would like to output 14*(7 - 2*sqrt(7)),

but Maple keeps returning 98 - 28*sqrt(7).
I have a double about this alternating series.
According to maple this series converges:


However limit ln(n)/n + 1 does not equal to zero, it equals 1. Therefore the series should diverge.

Also while I am on the subject of series and limits, why is limit (-1)^n  as n goes to infinity a range between -1-I and 1 + I.

limit((-1)^(n), n=infinity)
                        -1 - I .. 1 + I
