After recent (2.6.15.1600x64 or mayby also previous 2.6.14) update I cannot relogin. At first relogin seems to work (there is green ok symbol next to Log ot button), but I am unable to dowload or subscribe any account (there is continuous standby icon rotating next to subscribe button), location and hashtags however do download. After restart application opens in "not logged in" state. It is possible to subscribe and download profiles but only in "not logged in" mode. Changing to 32-bit version or downgrading to .14 does not help.
