Here is my experience of working with Ardor platform:
I installed it from https://www.ardorplatform.org/download-ardor-blockchain-platform for OS Windows.
I logged in there with my NXT wallet passphrase (not NXT address - it's important) where were all my Ardor assets and NXT coins.
It works! I can see all my Ardor (already coins) and Ignis which I get from holding NXT (to see your Ignis balanse You must switch from ARDR mode to IGNIS mode in upper left corner of node)
But here is my quastion:
I started forging (as I think) from the moment of Ardor mainnet launch, but still could forge nothing.
What am I doing wrong? Please, help.
As this is a proof-of-stake coin , the amount you earn forging is dependant on your staking balance. The reason you haven't forged anything yet is mainly cause there aren't a lot of transactions on the network yet and also cause your staking balance is likely small so you're getting outcompeted by bigger players. I suggest using a forging pool. Look up this one:

He ran the old NXT forging pool.
