Client stuck at 76%

[Legend]

When I bought my VPS, it came with a RP hotel set up on it. I want to change the emulator to my previous RP emulator (SpringEmu) as Spring is far more stable. When I switch over to SpringEmu, the client will get stuck at 76% and I can't find a cause. One thing that looks weird is that there's a port in the emulator's config file (30002), but when I change it to 30000/30001 it breaks.

Any ideas? I can post my emulator config or whatever need be.
