After updating the LA portable version, it won't start.

[Gintaras]

Rename (backup) your portable folder and run the portabe LA setup tool. Delete the \files line. Portable LA then should work.

LA does not create error logs, but .NET usually writes to Computer Management > Event Viewer > Windows logs > Application.

Also you can tell Windows to create a .dmp file when LA crashes. Then send it to me. Often it is useful.
