Problem starting MySQL

[islanublark]

Hi all. I have some issues when starting MySQL at XAMPP control panel, version 3.2.4. Its seems to start just for a second and after that it stop and show me an error. I hope you can help me with the problem. I´ve been working with XAMPP for months but three weeks ago this problem started happening and since then i can´t launch MySQL.

I left you here the logs that i got when i try to launch it.

Screem of XAMPP control panel:

I have exactly the same problem since one week, I would expect this to be a common defect. Any user on this forum who can help us out?

Yesterday XAMPP works fine but today i see that :

Anyone know what happening and what need to do ? Il try up memory:
# Uncomment the following if you are using InnoDB tables
#innodb_data_home_dir = C:\\mysql\\data\\
#innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend
#innodb_log_group_home_dir = C:\\mysql\\data\\
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
#innodb_buffer_pool_size = 2048M
#innodb_additional_mem_pool_size = 50M
# Set .._log_file_size to 25 % of buffer pool size
#innodb_log_file_size = 100M
#innodb_log_buffer_size = 8M
#innodb_flush_log_at_trx_commit = 1
#innodb_lock_wait_timeout = 50
And nothing happns (((

A lot of people have the same problem, but anyone know how to solve it?

[padtiepancake]

I'm here with the exact same issue.

Maybe I can bump this up again.
