Exporting All Test Suites

[TenaciusGordon]

Hello,

When I try to export All Test Suites of my Test Project I get the following message:

ERROR ON exec_query() - database.class.php
1 - Can't create/write to file 'C:\xampp\tmp\#sql_a28_0.MYI' (Errcode: 13) - SELECT U.login AS updater_login,users.login as author_login, NHB.name,NHB.node_order,NHA.parent_id AS testcase_id, tcversions.*, users.first AS author_first_name, users.last AS author_last_name, U.first AS updater_first_name, U.last AS updater_last_name FROM nodes_hierarchy NHA JOIN nodes_hierarchy NHB ON NHA.parent_id = NHB.id JOIN tcversions ON NHA.id = tcversions.id LEFT OUTER JOIN users ON tcversions.author_id = users.id LEFT OUTER JOIN users U ON tcversions.updater_id = U.id WHERE NHA.parent_id = 143 ORDER BY tcversions.version DESC

Is this a bug?? or I am doing something wrong??

Thank you
