open up eq2map_config.cfg in C:\Program Files\EQ2MAP Updater\ folder (use notepad to open it) and look for the lines that look like:
Code:
<ConfigValues>
<OptionName>AutoLaunchPath</OptionName>
<OptionValue>C:\Program Files\Sony\EverQuest II</OptionValue>
</ConfigValues>
<ConfigValues>
<OptionName>AutoLaunchFile</OptionName>
<OptionValue>EQ2.exe</OptionValue>
</ConfigValues>
<ConfigValues>
Make sure that these settings are correct. The AutoLaunchPath should be the folder location where eq2.exe is, and the AutoLaunchFile should be the name of EQ2.exe (in case you renamed it).
