Help! i can't insert a large text file into my MYSQL database using sqlbuddy.

[Sly]

I am kinda new to PHP, and SQL, as such i believe i might be doing something wrong. I have created my website and i have designed my database (MYSQL). I haven't had any problem with SQLbuddy until today when i tried to insert a TEXT datatype into a row in my MYSQL database.
*I am using wamp server version 2.2, mysql version 5-5-24, and sqlbuddy version 1.3.3.
* I created the column using this command: "ALTER TABLE table_name     ADD COLUMN column_name TEXT NOT NULL;"   (pls note here i have used "table_name" and "column_name"  instead of the actual names i used). Now i am curious to know if there is anything wrong with my use of the "TEXT" datatype in the above statement.
*After creating this column, i now tried to enter my hand-written text using this command: "INSERT INTO table_name(column_name)   VALUES(' here i typed a text with about 5000 characters '); "

I realised that when i try to insert a small text (about 500 characters), the text is smoothly inserted into the database without any problem, but when i try to fit in a larger text it gives me this error message "There was an error receiving data from the server" Now i have no idea what this  is about. i have spent 12 hours today on this single problem....i have tried using a larger datatype such as "longtext " but i still get the same message when i try to insert a larger text in the database.

I have been using sqlbuddy since i started my study and i have come to like it, that is why i am reluctant to try out some other program. Any imediate response would be greatly apreciated. Thanks for your time and excuse the poor grammar...i am just frustrated!
