Can't enter info into GW2 client??
Perhaps, a -repair of the client? The fields should not be small. Or check your resolution?
Top/Bottom of Page – Support – Search (Repair)
Good luck.

tried both of those options
That does not look like the launcher you should have. Maybe try downloading the launcher, again, from the official site.
Or, contact the Tech CS Team and ask for assistance. Top of Page – Support – Submit a Request
Good luck.
