1054 Uknown Column

Hello everybody,
First instalation and Joomla version 3.3.4(just updated. I have 4 databases in the joomla folder localhost and tried making my first table but this occured:
1054 Unknown column 'Ώρες Διδασκαλίας / Εργαστηρίων / Φροντιστηρίων (εβδ.)' in 'field list' SQL=SELECT `Τίτλος Μαθήματος`, `Κατηγορία Μαθήματος`, `Ώρες Διδασκαλίας / Εργαστηρίων / Φροντιστηρίων (εβδ`.`)`, `Πιστωτικές Μονάδες`, `Διδάσκοντες` FROM `πρώτο εξάμηνο` ORDER BY `Τίτλος Μαθήματος` ASC LIMIT 0, 20

There are some greek characters in there cause the project is greek and i have to deliver it in 3 days so I'm kinda in a hurry
Thanks in advance,
Vag

Because the project is due in two days I'll have to ask for a full refund if my problem isn't solved till the end of the day.

Regards
Vag

Thanks for your reply. I'll try to change them and see what happens tomorrow. I'll post the result
