Hi,
I see sometimes users have difficulty in obtaining updates. To identify the problem I deleted a module just received through the system upgrade and I got a problem!

I don't see the module in "Process", I see module in "Installed Packages", PI gives me a "There are no updates currently available for your PixInsight installation."
OK, now solution:
1) Go to PixInsight folder and edit file updates.xri ( i do it in PI Script Editor )
2) Delete in the file a section with problematic module. For example if you have problem with CosmeticCorrection module look for the code:
<package fileName="20120404-1-windows-x86_64-module.zip" sha1="3bf7f85adcce9a6d76ed50209f28bb455e871259" type="module" repo="http://update.pixinsight.com/" releaseDate="20120404" installDate="20120410022559">
<title>CosmeticCorrection module version 1.2.0.3 (new module)</title>
<description>
<p>This update installs the first official version of the CosmeticCorrection tool, written by Nikolay Volkov. Although this tool is relatively new and is still undergoing extensive development, it has already reached an excellent stability and usability level.</p>
<p>CosmeticCorrection allows you to fix defective pixels (hot and cold pixels) as well as column and row defects in your images. It work on monochrome CCD and OSC and DSLR CFA mosaiced images as a batch process, and has full real-time previewing capabilities. CosmeticCorrection has the potential to become an essential preprocessing tool in PixInsight.</p>
<p>For more information on the development and features of the CosmeticCorrection tool, please refer to the corresponding thread on PixInsight Forum:</p>

</package>
and remove it completely.
3) Save file and check updates. PI should restore the module.
Best regards,
Nikolay.
