Hi Sawman,
Sorry for the tardy response, been driving back from France yesterday afternoon and today. I was thinking about your clutch problem en route and thought that another problem may be the friction plate sticking on the splines of the gearbox input shaft. I've just read the posts referred to by Andre44 above and this is also suggested by Guten. As Guten says this can cause the friction plate to drag on the flywheel or pressure plate and make it difficult for the synchromesh on the forward gears. Cleaning and/lubrication of the splines is probably a gearbox out job though. You don't want to risk contaminating the friction plate by trying to spray lubricant from an access point in the bell housing (e.g. where the release bearing actuator arm enters). I'd still try for some cable adjustment first though, just in case it works. It would be a lot less hassle than a gearbox out job.
MZ.
