Still no idea what you are talking about? Can you please just post a simple version of the problem with system used and what you have tried?
Because this is what I got: You can not reinstall a palace client and have no palace installed but get error messages when using palace?!?! And the error you post is from the openpalace flash client so... what is going on?!?
Can you copy paste "those error messages" because I'm afraid I don't know about "those" eeehm.. be specific please.
Just in case I guessed right and you are looking for a client download: the download page I posted works fine on my mac and windows & computer so no idea what is up, here is a copy of the links on that page:
New Palace clients
PalaceChat Windows
Phalanx full install Windows
Classic Palace Clients
Windows Palace Cliet 3.5.1
Windows Palace Client 3.6
Special versions
NO installer Windows Client 3.5
Windows Palace client for BOTS
Perhaps Windows is blocking the page because it has links to .exe files, good luck, hope this helps?!?!?!
