Gravity Forms problem

Gravity form was working for a while, but a problem happend. All forms, posts, pages were gone like that! I tryed to deactivated the plugin and it didnt deactivated. So, I access the FTP client and remove it manually. All things got back to normal, all my posts back, pags, etc.

I downloaded the new version 1.7.5 and installed it. Same thing happend, as soon as a activate the plugin, everything goes away.

I've tried one last time and that time that apeared in plugins screen in wordpress:

WordPress database error: [MySQL server has gone away]
SELECT option_value FROM wp_options WHERE option_name = '_transient_gform_update_info' LIMIT 1

WordPress database error: [MySQL server has gone away]

What can I do to fix this?

ok, this page solved it:

BUT, this is a workaround. after update wordpress it'll happen again. and from start, it's not should be so ugly solution.

for administrators :
can someone point the REAL problem? and why it worked fine untill today?
after some reading in google for "MySQL server has gone away" i understood that maybe there is a code in gravity forms that take too much time after open connection. can this be true?
if so, maybe reopen connection right before sending data to mySQL (if closed..?) ? or shorten code somehow?
