MISSING IN DATABASE alter table

[Kupido]

Hello

i created many custom fields, and with the last i had a problem.
In the Studio i get no error msg.
But then i change some data in contacts, the changes were not saved in the contact.

In the admin i make a fastrepair and get this error message.

in phpmyadmin i make the direct in sql the command

alter table contacts_cstm add column innendaemmungart_c varchar(255)  NULL ;

and get the following message
#1118 - Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. You have to change some columns to TEXT or BLOBs

i read http://dev.mysql.com/doc/refman/5.0/...unt-limit.html

So i had the limit reached?
any Idea were i can add my custom fields in another way?

System
ubuntu
SugarCRM 6.1.4
and also tested with 6.1.6

thanks and best regards
