Issue with updating packages

Hi,

I have my token file in the correct directory.
However everytime I try to update a package I get this message.
I use github to login… and this was not an issue until about a week ago.
Here is an exmaple:

(v1.2) pkg> update Atom
Updating registry at C:\Users\a\.juliapro\JuliaPro_v1.2.0-1\registries\JuliaPro
Updating git-repo https://pkg.juliacomputing.com//registry/JuliaPro
fatal: ArgumentException encountered.
Value cannot be null.
Parameter name: Username
Parameter name: operationArguments
Resolving package versions…
Updating C:\Users\a\.juliapro\JuliaPro_v1.2.0-1\environments\v1.2\Project.toml
[no changes]
Updating C:\Users\a\.juliapro\JuliaPro_v1.2.0-1\environments\v1.2\Manifest.toml
[no changes]

Any ideas waht’s going on?

thanks,

A
