Sorry to have to post this but I seem unable to install Hika Auction and have been looking for any documentation on how to do this. If I try to install it as an extension I simply get an error message: Table 'dbs5213379.v638a_hikaauction_config' doesn't exist but without any documentation or guidance I'm lost. I've uploaded it by ftp to my server but how do I run the install.php file to configure it? Already having charset issues so apologies for sounding thick but I'm out of my depth. any links/advice would be much appreciated. Thank you.

Thank you. Now I have Charset errors, I can see some posts explaining but cant get my head around altering the tables in the database. Will post error messages when I get back to the pc.
