Please first check the knowledgebase - it is searchable, and it has answers to common questions about product updates, re-downloading the products, current product version numbers, manuals, scenarios, driving and control questions, and other product support issues.
If you cannot find the answer in the knowledgebase, please submit a ticket via the helpdesk, making sure to choose the relevant category and product.
I get literally hundreds of emails a day about my products. You are more likely to get a reply using the helpdesk than a personal email now.
Patches for various products can be found in the knowledgebase: Patches
