Oops, the "1.4d" was a typo and never even existed. 1.3d is the most recent version and compatible with Strive 1.0d. I've now updated the description.
As to know what is going wrong, like Ank said we will need information from the logs, but my guess would either be you don't have the latest version of Strive or there are conflicing mods. Unfortunately pretty much most of the mods conflict with each other.
