V29 problems



I am due to upload my last two payrolls of the 22-23 ty and have just updated (as prompted) to V29. Now when i'm trying to enter payments for one of my payrolls, nothing happens. It brings up the prompt about those who are on hold, i press okay but then nothing happens. 

I've gone into 'check for updates' and it's brought up versions 26-28 for some reason, so now I don't know what to do. 

Please help.
