Hacking Question Games don't work after upgrade to 8.1.0

[Sevroo]

I upgraded my switch firmware from 7 to 8.1.0 because some new games didn't launch.
I downloaded latest kosmos with atmosphere via sdsetup.com and hekate 5.0.1.
Now every previous installed games show error "Could not start software. Please try again from HOME Menu."
When I try install new nsp it shows Error: 0x291 / Module ETicket(145)/ Description: Unknown or undocumented error(1)
What to do ?
Maybe I do something wrong witch hekate. When I press launch in hekate 5.0.1 there are three options CFW (SYSNADN) CFW (EMUMMC) and STOCK (SYSNAND). I using the first two and it is the same.
Please help.
