Thanks for all the replies!

I tried updating to 0.5.19 and that showed my funds, finally.

Now quickly transfer this to MultibitHD and never use the classic version again 

Thanks again.

I got a multibit classic wallet with some bitcoins in it (or rather: there should be some in them). They are only visible on the blockchain but multibit 0.5.18 says I don't have any bitcoins while my latest transaction was me receiving some?

I've been resetting it for the past 2 days taking about 40 minutes every time and it never helps. Multibit HD killed the option to import multibit classic wallets or private keys so they are useless.

What can I do to get my money? Is it just lost because some developers decided they stopped supporting a wallet function? I got a multibit.wallet file but I have no idea what program allows me to import that (except for multibit classic which says I have 0 bitcoins).

Edit: I see I posted this in the wrong subforum, can a mod move this?
