As MTU sorted my registration problem today, i have been able to install hoster on my desktop system (AMD 4gb cpu, 1gb ram and XFX gforce 9750 graphic's)
Hoster 4.06 apears to run in sync ! which means H4.x has probably exeeded my sad laptop's limit's
64mb of shared Video ram.
So members that suggested 64mb shared video memory could be my problem seem to be correct.
By the way, Thanks for all your reply's everyone
Are there any members who can run hoster 4x on a laptop without sync issues ?
Dave.
