Probably the issue is related to the .dll files of Store Manager installation.
The issue may be resolved in 2 ways. The 1-st one is: click at the shortcut of Store Manager for PrestaShop with right mouse button > Properties: http://screencast.com/t/ChYAwpjExAo
Click at Compatibility tab and make the Store Manager compatible with Windows XP (Service Pack 3): http://screencast.com/t/OU9jWhHC4p
The 2-nd option.
Please go to C:\Program Files\eMagicOne\Store Manager for PrestaShop\Plugins and delete the unused .dll's containing in Plugins folder.
There are .dll files for Store Manager's addons like:
DOBA Integration addon - "DobaIntegration.dll";
eBay Integration addon - "eBayIntegration.dll";
ICEcat Integration addon - "ICEcatIntegration.dll";
Peachtree Integration addon - "ptIntegration.dll";
QuickBooks Integration addon - "qbimportexport.dll";
USPS Shipping Integration addon - "StampsIntegration.dll";
PDF Catalog Creator - "PDF_Catalog_Creator.dll".
Please select a few you do not need and delete the .dll files (at least 3 of them).
If you issue remains after deleting the .dll files, you may try to update the Store Manager to the latest version, where we have implemented a new connection components.
