ISTA 4.52 Error with full PSzD - sec4diag.otherexceptions

[viltsone]

Hi!
I have the same problem. I am using ENET cable. At first I did not have the problem but after making changes in Reg edit Rheingold files it poped up and I can not get it back anymore. Now all the time sec4diag.otherexceptions
At first I had also another popup connected via ENET and it connects and shows all vehicle info but then comes up with 'The programming system could not be initialised. The ISTA installation may be damaged or incorrectly configured. Reinstall ISTA. If problems persist, contact local support.'
What changes are needed to make in registry or some confic files? 

Installion directory is C:\EC-APPS\ISTA
