What patch are you for your ALM 11.0? Just asking as if on 17 or higher, you could upgrade to Sprinter 12.01 (and would have to upgrade UFT as well).
For issue number one, you need to get patch 25 for Sprinter 11.52. This patch has a fix for the decryption error. That one is typically LDAP related, so guessing you might use LDAP authentication for ALM.
For issue number 2, this could be due to a few things. One is to check permissions.
See this post for exact required user permissions for the ALM user group:

If user group permissions in ALM check out, suggest you try the following. Uninstall Sprinter. Ensure UAC is turned off, and then reinstall Sprinter with an admin account. Often the ''unspecified error'' issues related to non admin install and UAC blocking parts of the install.
If you do the reinstall, as Michaeldx mentions, you will then have to go about repairing UFT. UFT and Sprinter use many of the same client components so it can be tricky to get both working well on the same computer.
