Sky/OneDrive not syncing

Until the other day my drive was working perfectly. Since then I have made no changes to the system, but syncing has stopped. The drive icon constantly says checking for changes and then appears to crash. It has also started "finding files" and i am unable to change options to view online of offline while "setup is being completed" the trouble is it never completes... I can add docs etc from the web and it will sync on other PCs but my win 8.1 tablet refuses to play ball. I have spoken with Microsoft and they want me to pay for the solution (maybe). I have tried the troubleshooter but no luck. I'm not a dummy but this one has got me stumped. Any help please I really need this solved ASAP...

Have you tried uninstalling the OneDrive app on your tablet and then reinstalling it?

No was trying to avoid having to do that. Do you think that uninstalling would solve problem?

There is a good chance. But you might want to hear what some other members have to say.

Yeah. I appreciate your help. But before I uninstall/disable etc. I might just wait and see. Thanks for your suggestion though. More help than Microsoft... *******s, make me pay to solve issue...
