Login Problems Lumia 620 Windows Phone 8.1

[rukhh]

Hello!

Spotify Windows Phone Version has been running till the great Update. Now i am not able to login and connect the device to my account.

After entering my credentials and click on the login-button it greys out, the waiting bar displays and nothing happen. It stays in this state (greyed out and waiting bar) still i kill the process.

I´ve tried the following:

- WLAN / 3G

- My connected device list contains only one device, so there might be not problem

- reinstall severeal times

- switched install location from phone storage to sd and back

Are there hidden cache files from the old version which might cause this problem? I am clueless...

Please provide my a solution. Thanks!
