Problem on installing ibProArcade in VB 4.1.2

Hi ,
sorry for my bad English
I have installed ib Pro Arcade in my forum ,
I have uploaded all files , and imported xml , but there isn't any change in admin cp and when i go to arcade page i get this error

Not Found

The requested URL /arcade.php was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

I 'm sure i have uploaded all files and there isn't any thing wrong.

What should i do??

Thanks in advance

Make sure you uploaded the admincp/arcade.php file..

same error here all files are uploaded, i also got blank pages in my admincp

[Hippy]

are you uploading one at a time ?

open the zip file..
extract it to your desktop..

now open ibProArcade2.7.0+ folder , you'll see a folder called upload in there
highlight everything in that folder and drop into your forum root dir ..
the files will go to the correct directory's

have done that already but i get a 500 server error and if i check admincp the arcade option is shown but when selecting for example main settings it results in a blank page

[Hippy]

did you import the xml file ?

[owning_y0u]

i have imported it. even removed it afterwards and re-uploaded all the files and then re-imported the xml

[Hippy]

with out seeing where you put them I can't suggest much more..
if they are in the correct place all work..

it is in the spot where it should be. i used to have it working on 3.8 ;-) and there isnt much difference in the install method between 3.8 and 4.x.

Theres two arcade.php files..

One goes in the root and the other in the admincp folder..
If you get a blank page or 500 error,,that would be caused from not having the arcade.php file in the admincp folder..

The one that goes in the admincp,,,at the top of it,,should have..
// ibProArcade Administrator Control Panel for v2.7.0+
