Hello Matt,
The latest version of Dynamic Registration available is 4.2.3. You should log into the store.dotnetnuke.com with the account that you used when purchasing Dynamic Registration 4.2. You should see this patch 4.2.3 under your downloads. Download this and install it and let me know if this assists.
The latest version of Dynamic Login available is 4.1.51. So you would need to upgrade from 4.0 to 4.1. You should receive a 70% discount when purchasing Dynamic Login 4.1 since you have purchased Dynamic Login 4.0, please review our upgrade policies/discounts:
http://www.datasprings.com/support/...ade-policy To receive this discount, please be sure to login as the same account as when you purchased Dynamic Login 4.0, otherwise there will be no record of your previous purchase and the discount will not be applied.
Please install both of the versions of our modules listed above to ensure you're on the latest releases. If you continue to have issues, we'll need specifics as to which sections are not compatible within IE 10.
Let me know if you have any questions.
Thanks,
Ryan
