Can not login into Composer

Hello Everyone,

I am not able to login into the Thingworx Composer. After entering the correct username and password the login window disappears and appears again but with blank fields and nothing happens.

I think it is because I disabled the PTC.login.Authenticator (I think its called like that but I am not totally sure), while I had access to the Composer. Apparently I can not login with my credentials with the Authenticator being disabled.

Is there a way to activate this Authenticator e.g. via a Rest Call? Just like it is possible to update property values or execute services I hoped I could enable the Authenticator again.

If anyone knows which call I should make and what the exact name of the Authenticator is, please let me know. I am also open for other approaches to tackle my problem.

I am working with a Trial Version of Thingworx btw. and I do not have Administrator Rights (because I am using the Composer for Thingworx Studio - AR application)

Best Regards,

Dominik
