severely disappointed as i just received this from ebay and was really looking forward to using it and it was described to be in fine working order. anywho, everything seems to be functioning fine except it doesn't play or record. from what i can tell the mechanism (sorry, not sure what it is called) that pops up into the cassette itself is stuck in the 'up' position so i can't even get the tape in or out. i manually retracted it to put a tape in to see if it would record or play with the cassette loaded but still it would do neither and it was a nightmare getting it back out. rewind and fast forward are working fine. any ideas would be greatly appreciated!!! i really want to use this.
