Nitro 13 Pro Freezing when login to my nitro sign account.

[PURIFICACION HERRAOR GALLARDO]

Morning, 

I've been trying to fix this error since past friday and I didnt find the way to fix this, I've tried in different computers and the problem persists.

The problem is, as said in the title, that when I try to login up with the Nitro Sign account, it freezes, dont log in and I can only close the program using the task manager.

It seems that Nitro starts to open "Nitro Sliders" within the problam, several ones at a times, but noone of them show up in the actual session.

I've tried also clean installations and I've used your cleanup program that I have seen in other similar topics, and did not work.

Any help would be appreciated.

Thanks.
