Update to new version
v1.1.7
v.1.3.2
Windows 10 1803

There has been some recent changes in how we handle updates.
Could you try:
and see if the problem persists?
I have the same issue. Updated PC version when prompted and now it's left both a 1.1.x version that i cannot log into (incorrect login credentials it says) and the new updated 1.3.x version (which works but slow).
I'll try uninstalling both and installing latest release.
[Fixed] for now.

the new updated 1.3.x version (which works but slow).
You might be experiencing #1057. This will be fixed by #1073 (will be released soon as v1.3.4).
