We want to move from x86 to CCR1036 dude server, but we stuck.

Dude is working for years on x86. Current version is 7.12.1 and working.

We export dude db and import to CCR (tile) with no errors but Dude Client is crashing on login. Dude server is up and running and we can see network maps and everything via web.

What can be the problem ?

We tried clean dude install on CCR and client is stil crashing. On x86 everything works with no problems.
