I've had some.....the kind word....."difficulties" with V18 since it's initial update months ago. Updating came about with a series of Start Pages that allowed SoftPlan couldn't connect with Softplan.com.
The 18+ tech support suggested making sure that SP was a default program that would communicate through the Firewall as well as knocking back ad, mal and virus-ware defenses. Nothing worked....just starting up on this computer (my Thinkpad T510) in the free downloaded version of 10 when it came out a couple of years ago....just opened up the Start Page; but nothing to sync up to as 18+ was out of contact.
I'm doing another update today via a new Tech at Softplan that so far....has found related some issues that are jiving with the existing set up. Most of it deal with 10 and updates v. Windows Explorer. It's looking for version 11 with the newest 18 update....and set up. It's been a major SNAFU for the past few months but as the current 10 update is loading, hopefully with a re-check on defaults and latest 10 updates....it'll be ready to go back to work and take some of the time off of the workstation that gets most of the daily action.
I've noted...conspicuous by its absence....this problem with anyone else here or in SPLASH. The purpose for the note...just searching around for other users that dealt with and resolved their issues. Thanks!!
