Help Multisell Manager 1.2 by trex

[rtcxool]

Hi,  I know a lot of topic already about this L2 Multisell Manager 1.2 by trex,  but none has an answer ! Looking 3 days now,  tried everything and still have an issue..

So I used this program few years ago and I liked it so much. I'm trying to install it now. I've imported sql file to database trough Navicat, succeed,  no errors.  I updated option.ini but when trying to open program I get this message:

Could not connect to  database! Please check your connectionsData and try again!

I know it looks like option.ini have wrong data,  but I tried everything!

MySQL Server: localhost (as well tried 127.0.0.1)

MySQL Login: root

MySQL Password: root

MySQL Database: l2jdb

Tried 100 times in different ways,  IP with dots spaces before after etc etc.. as well tried external IP. Still same issue.. It's so strange,  Nivicat connects to database with no issues with same details,  and this Multisell program fails. 

Even changed MariaDB to MySQL 8.0 as I though maybe MariaDB causing this issue but not,  same issue with MySQL..

As well tried to download this tool from 4+ different places,  just in case if broken program files can cause issue but not, none is working

 

Does someone know what it might be?

I really need this tool.
